ExpressionParser: Search for control names first

Otherwise, valid control names like "Cursor X+" would be incorrectly
tokenized as "`Cursor` `X` +", causing the parser to first abort trying to
find a control named `Cursor` rather than aborting with invalid syntax on
the bad binop.

We could also do this by resolving devices lazily, but since simple
control name bindings are going to be 90% of usecases, just look for these
first.
