The existing Simple templates did not address the issue of CF names with spaces in them. This strips non-word characters to establish the variable name -- a trasformation which might cause duplication of CF names, but this does not notably worsen the situation, as they did not already posess any uniqueness guarantees. Note that this may still lead to unicode variable names, as \w is UTF-8 aware, allowing for the variable "$TicketCFStraße". Fixes I#18446.
