Sol.config.ChangeTab

Sol.config.ChangeTab = function(addonName, tab)
If your config page has multiple tabs, you can use this to switch
between them. 
Parameters:
+ addonName - Your addon's name
+ tab - The tab button to change to (frame element, not string)
PRE: Your XML must have tabs and pages, the tabs most likely being buttons
and pages being the frames you'll be switching in and out using the tabs.
The pages must be named exactly the same as the tabs except wherever the
word "Tab" appears in the tab name, the word "Page" should appear in the 
page frame (case-sensitive). For example:
<Button name="MyAddonTabsFrameTab1">...</Button>
<Frame name="MyAddonPagesFramePage1">...</Frame>
POST: Changes the tabs to make the selected one stand out and hides the 
previous page and shows the new one.
