This patch requires patches 0 through 1.

Fixed a "*" in --displaysyntax that should've been changed to "default" in the nano-1.3.0-color-0.patch patch.
Disallows syntaxes named "none".
'-Y none' disables syntax highlighting.
New 'default-color' directive defines a color for all unmatched text. Can be used to catch errors in simple syntaxes, such as nanorc.
--displaysyntax now displays syntax extensions.
Aborts the current color when a zero length match is found instead of continuing to look for more matches with what is probably a bad regular expression.

Errors when a syntax name is redefined.
Uses syntax override when present even when a definition exists for the file extension.
New 'default-syntax' directive, applied to files that don't match a syntax.
New 'icolor' directive for case-insensitive matches, same format as color directive.
New 'include' directive based on the nanovarcinsert patch. Modified to only include files containing color and icolor directives. Errors when called outside of a syntax directive.
New '-d' and '--display-syntax' options to display syntaxes for testing purposes and then quit. Displayed in a grep'able format `nano -d |grep "^html:"`
Only stores compiled regular expressions for syntaxes that are in use.
The new regular expression code reduced the memory footprint by 1.3meg with my nanorc file. I used it to write most of the code in this patch and I had no problems. This patch does not fix the regexec() memory leak.
