Connor Olding 8546411e14 handle ; comments in variable definitions again 
this is hacky but i don't wanna break existing code.
if you used // comments, then you'll have to change.

Connor Olding cdc0f8edb2 add a barebones expression parser 
at the moment, this probably only works in directives.
some of the operators are still unimplemented, and the errors are poor.
there will be support for accessing variables in the future.

Connor Olding 7ccc2b180f rename "defines" to "variables" 
this follows bass' terminology:
constants don't care where they're defined, but can never be changed.
variables must be defined before use, but can be redefined.
defines aren't necessarily numbers.

Connor Olding fffe542d10 fix most line numbers in errors
