[bugs:#817] Crashes caused by Device Names that were allowed at creation time.

This problem is related to creating new device servers; we detected that some characters (e.g. spaces and dots '.') are causing problems to both Jive, Astor and Starter. Max IV already had problems with accents and dots in the past and now we experienced it due to Astor finding dots in starter names.

We think that the easiest solution is to not allow the creation of devices if the name contains spaces or a character that may cause conflicts (e.g. ~.'*&^$%#@)).

We think that only english alphabet letters (without accents), numbers, dashes and slashes should be allowed at creation time; thus raising an exception if found.

Sounds reasonable. I would also add underlines so that the a matching regexp becomes:

^[A-Za-z-_0-9/]+$
