consistent handling of exit arguments

[Chris]

Allow all forms of directions to be provided as inputs for lua functions (numeric, long, short). Will take the form of a general handler each function calls.

[Chris (chrismudlet)]

Some research reveals these as the commands which will be expanded to accept all directional possibilities:

setExitWeight - takes string, command passed as string
addCustomLine - string direction, command passed as string
setExit - number, dir passed as #
lockExit - all #'s
hasExitLock - all #'s
setExitStub - all #'s
connectExitStub - all #'s
