C++ Fix for #47

[matter123]

This provides a C++ fix for #47.

Additionally, this improves highlighting of inherited base classes. Previously only 1 base class per access specifier was allowed. This PR extends that to any number of base classes.

This does not fix the same issue in the C grammar.

I added tags to the colon and the commas. Other than that my changes were basically just moving code around. Great job 👍

You shouldn't need the complicated Regex on https://github.com/jeff-hykin/cpp-textmate-grammar/blob/b1b034011874d96e10ecc9a42a87771fbe800748/generate.rb#L891 patterns are matched in order so : is excluded from the includes, , and access specifiers have already been matched and are excluded from the regex on Line 891. All that is left is spaces and variable_names. I think the current regex on Line 891 tags the spaces as part of the inherited class name.

Yeah for your original one you're right it's not needed. I abstracted out the inhertance_context though so it could be used in two different places, and the second place is when the complex regex is needed.

Right now:

With the complicated regex:

Without the complicated regex:

The reason I did the abstraction is because your pattern matching was better, and it could be used in 2nd place.

I appreciate you looking over the changes though 👍

Ah, okay. You might still want to fix the regex tagging the space before the inherited class, however.

Good call, I missed that. Next time I'll post my changes for review Haha.
