ggtags-fontify-code should be called optionally

Some may prefer no highlighting at all. Also, some modes require (significantly) more context for proper highlighting than just a single line[1]. What about a variable to configure the behaviour? Something along these lines:

ggtags-maybe-fontify-code:
t: Fontify if the code buffer has font-lock-mode switched on.
nil: Force off

[1] I guess loading the entire file into a temporary buffer, highlighting and extracting the string with text properties might be too expensive in case of large files.

The plan originally was for people to use (add-function (local 'ggtags-get-definition-function) ...) to override the default.
Alternatively you can defalias ggtags-fontify-code to identity.

Yeah that would work, thanks. I guess having a switch for the default implementation won't hurt though.
