[PATCH] xconfig: Set configuration strings on focus lost

["Peter Kümmel" <syntheticpp@gmx.net>]

A change to a string configuration is currently only
recogniized by pressing enter/return. When you just
click to another entry after the string was edited
the change is not set. Additionally when you come
back to the string configuration your changes are lost.
With this patch the string changes are automatically set
when the focus leaves the edit field. There is still
the possibility to drop any changes by pressing ESC.
