Autoloading lexers

[onemanstartup]

Memory with loaded lexers ~> 3Mb
Memory without ~ 0.5Mb

It is not much, but gem by gem..
It is many ways to do it, but it possible. Rarely people use all lexers.

Hm, yeah, this is becoming a priority as the number of lexers increases

Just found library for autoload, it may helps. https://github.com/njonsson/autoloaded

It's a bit more complicated than that, I'm afraid. Lexers aren't just accessed as constants - in fact, more often they're accessed by tag or alias, as in Lexer.find('rb'). So there's gonna be a bit of shuffling around of data to do, and that's gonna take a bit of design work.
