Is it necessary to remove it from the keyword list? Turns also syntax highlighting off.

[Bertk]

Some unit test fail as soon as the CxxKeyword.TYPEID exist.

[guwirth]

CxxKeyword.values() is in use by lexer and syntax highlighting.
If we want different lists we have to split this.

[Bertk]

We should add a string array or collection for highlighting purpose in class CxxHighlighter and add strings used within the CxxGrammarImpl rules.

@Bertk could you rebase this please. Will add it to RC3 this evening.

[Bertk]

@guwirth Done.
