enable more Meade commands

[peteasa]

We have found it convenient to be able to send more Meade commands via the INDI Control Panel
The following commands are added

:XSRn.n# :XSDn.n# :XS... these command do not return values:
WARNING 564.754999 sec : Executed Meade Command error: -4 :XSD317.2# -> ''
WARNING 530.018348 sec : Executed Meade Command error: -4 :XSR315.5# -> ''

:Mgnxxxx# these commands do not return values:
WARNING 1022.177341 sec : Executed Meade Command error: -4 :Mgn0200# -> ''
WARNING 2372.737374 sec : Executed Meade Command error: -4 :MGN0200# -> ''

:MXxnnnnn# these commands return a character:
WARNING 509.919341 sec : Executed Meade Command error: -4 :MXd00100# -> '1'

:SCMM/DD/YY# these commands return a string. Other :Sxxx# commands return a character

Thanks, are the warnings in the log present now?
