[ic] typo/error in flex editor, v4.7

[sarah gargett]

I was having some problems trying to get the flex editor to read the
ui_class variable, when passed as a cgi variable, and found the following
typo in flex_editor.html:

Line 57 currently reads:
	[if !scratch ui_class][seti ui_class][either cgi
ui_class][or]Admin[/either][/seti][/if]
but should read:
	[if !scratch ui_class][seti ui_class][either][cgi
ui_class][or]Admin[/either][/seti][/if]
i.e. the closing bracket for the [either] tag and the opening bracket for
the [cgi] tag were missing.

I couldn't see any other reports re this typo on the mailing list, so I hope
this helps.
