Add guard to Alternative
...
The semantics are:
-if tag is Some(_), assume the condition is a constructor,
and compare tags
- if guard is Some(_), evaluate true/false *after* having
applied any bound variables
With this, I can technically get rid of bare conditionals now, since
they are the same as an Alternative with a None tag

Starting custom operators
...
Can now parse custom operators. Maybe I want to make it so that you
have to put explicit backticks if you define a custom operator,
currently you can just do: fn +() { .. }

Preliminary support for binops in if-discriminators
...
The BNF grammar is a bit more liberal than any successfully-compiled
schala program should be, in that it allows things like `if x < is
pattern`. It's okay if that parses successfully and then is an error at
typechecking.
