ExpressionParser: Suppport N-ary functions. Arguments are read LISP style. N atoms are read after the function name. Added "if" function and made the "while" function more sensible with an arity of 2. Removed the ugly binary conditional operator.

ExpressionParser: Replace the timer literal with a timer function that increases from 0.0 to 1.0 and resets after N seconds. e.g. (!timer 2.0) is a 2 second timer. Fixed parsing of unary expressions so things like (! ! 1.0) work.

ExpressionParser: Add !while loop unary expression. Limited to 10000 reps to prevent infinite loops. Rhs is re-evaluated until it is < 0.5. Added comma operator, which behaves like it does in c++. Added subration operator.

ExpressionParser: Renamed ControlFinder to ControlEnvironment. Added support for variables and assignment operator. ControlExpression objects now reference a matching input and output so the two can me mixed in any expression. (you can set rumble directly from inputs)

ControllerInterface: Make CoalesceExpression not set the inactive child's value (rumble) to 0. This caused rumble to not enable when a control expression was both a valid "bareword" and "complex" expression.

ExpressionParser: Rename ParseStatus' Success member to Successful
...
This clashes with X11's preprocessor define named Success (because using
non-prefixed lowercase identifiers in C was apparently a fantastic idea
at some point), causing compilation errors.

InputCommon: Extract ControlReference from ControllerInterface
...
Better separation of concerns. Relegates `ControllerInterface` to
enumerating input controls, and the new `ControlReference` deals with
combining inputs and configuration expression parsing.
