update to error classes, rework Param_Set_Multi

Added VMRemoteErrors.
Other error classes now subclass VMRemoteErrors.

rework Function Param_Set_Multi

added throw LoginError object on multiple login attempts (still crashing the powershell window during testing if in same powershell fork)

update readme to include vban_instream, vban_outstream example in set parameters by hash. macrobutton in hash can now use key button or mb.
