syntax: sql: colorize keywords regardless of case, and tweak the colors

Browse Source 
Make types a bluish green, for more contrast with strings, so that the
latter can be made greener, for more contrast with the yellow keywords.
Make the main keywords bluer and less bright, and unbold and soften the
yellow ones.  Soften the comments too.

Reference for case-insensitivity:
