StrPurge( char* text ): Fix incorrect behavior when string text is void.

Very minor enhancement in module edition dialogs.
Fix a minor bug in design rules editor: in Global Rules Edition: drill values > via diameter not checked
and the first item (track or via) in list was not checked (explains Bug 702177, that is not really a bug)
