Add __FILE__ and __LINE__ expansion to lexer. #51

I want to have magic tokens which are substituted for the current file name and 
line number so that I can write error routines which include this information 
such as

 raise ("Error %a %a"(.format @FILE @LINE ))

Although this can be extracted from a future backtrace object, it's very cheap 
to implement and might be fun.

i.e the same as cpp.

This would make it easier to unit test the basic line number catching. ie
1 # file is test-line-numbers.g
2 assertEqual @LINE 2
3 assertEqual @LINE 3
4 assertEqual @FILE 'test-line-numbers.g'
