* fix character literals (#\" no longer quotes the entire file etc.)
* properly nest block comments and support simplified datum comment
* add r7rs keywords, functions and directives
* fix identifiers
- pipes were not recognized as delimiters
- some valid identifiers were not recognized
- some were partially parsed as keywords
- quoting only worked on plain alphanumeric identifiers
* fix numbers (some valid numbers were not recognised)
* dont parse boolean constants as functions

text_object_word() was only sending the last part of a pathname to
vis-complete.
text_object_longword() is better, but sometimes may send a bit too much,
so leading delimiters for some languages are stripped additionally.

This allows to end PHP code sections. Otherwise token is treated as part of the comment and parser continues to parse whatever is after.

The color settings are currently stored in the `vis.lexers` table,
make sure it is not nil even when loading the lexer module (or one
of its dependencies e.g. lpeg) failed.

When the shell cannot find any matching files, the glob is not expanded,
and vis-open will return the absolute path of the current working
directory (because dirname outputs '.'), followed by the filename,
followed by a literal '*'. This commit checks that the final path
actually exists, and if not, exits with status 1.
It also uses text_object_longword for the range to match, so that
absolute paths are accepted, and replaced properly (else it only works
back to the first '/').

Both VB and LaTex use .cls file extensions. It should be a much more
reasonable default to assume LaTex syntax.

Use something like dos2unix(1) and unix2dos(1), if you
need to edit such files.

At some point it should probably be possible to add command prompt
bindings from within Lua. Currently there is no easy/realiable way
to detect the prompt window.
Should improve #526.

I think the default value for the cache argument to the lexer load
function should be true, not false. Optimize for the common case.
This makes the API ugly/harder to use. But for now we follow upstream.

Under presently-not-precise circumstances, regex patterns longer
than a screenful can cause first_match_pos to be nil. In this
sutation, evaluating `first_match_pos - 1' will be an error, so
jump to matchless case.

It is no longer possible to change the used syntax by assigning to the
`win.syntax = name` field, instead the function win:set_syntax(name)`
should be called.
The distinction between filetype and syntax lexer to use should probably
be clarified/cleaned up at some point.

Added all ANS Forth 2012 keywords as defined at
http://lars.nocrew.org/forth2012/core.html and removed keywords
that were not part of the standard. This necessitated rewriting
most of the Strings rules as well as removing some rules not
consistent with the standard. Only the s\" form should allow
escaping. The list of characters which may appear as part of a
keyword has also been expanded where appropriate.
Because '.' is a keyword as well as the first chatacter in a string
pattern, strings must now be given parsing precedence over keywords
to ensure proper highlighting.
A few errors were also fixed such as moving the true (which should
make keywords case-insensitive) within the word_match function's
closing paren. Parens have been removed from the operator list and
moved to their correct place as the delimiters for block comments.

Use pull instead of push based model for display code. Previously view.c
was calling into the ui frontend code, with the new scheme this switches
around: the necessary data is fetched by the ui as necessary.
The UI independent display code is moved out of view.c/ui-curses.c into
vis.c. The cell styles are now directly embedded into the Cell struct.
New UI styles are introduced for:
- status bar (focused / non-focused)
- info message
- window separator
- EOF symbol
You will have to update your color themes.
The terminal output code is further abstracted into a generic ui-terminal.c
part which keeps track of the whole in-memory cell matrix and #includes
ui-terminal-curses.c for the actual terminal output. This architecture
currently assumes that there are no overlapping windows. It will also
allow non-curses based terminal user interfaces.
