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 f851540b24 various fixes, mostly for labels 
reimplement modulo by 0x80000000 for labels.
allow numeric label values ("REL") to be "fixed" to bypass label calculation.
add offsets after label calculation instead of before.
properly check for EOL after all expected arguments have been exhausted.
finally, add token properties to debug dumps.

Connor Olding d10c0f0ee9 use Base class pattern; extend off existing classes 2016-04-20 13:15:17 -07:00
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.
