Downgraded required .net to v4.0.

Added suppoer for "Handbox" custom action
Changes how the focuser in and out functions.  Now sends multiple :F+/-# and multiple stop commands to help get over problems with the #909 missing commands.

Added support for checking for the older firmware that does not support the guiding commands, so uses guide rate slew instead.
