Refactor OptionsFrame.py

Rename all <Name>Panel to <Name>Tab
e.g. AudioPanel -> AudioTab

Now every Tab inherits from TabPanel class

TabPanel class contains all the methods to
create widgets, disable them, set the sizers etc

Moved almost all magic literals
(strings, numbers, etc) to class level

OtherTab:
	Renamed to CMDTab

OutputTab:
	Change output format pick from
	checkbox to radiobutton
