Room names should be strings

[sbecot]

It is possible to create room named with a string but only numbered room are listed.
A room name should be a string. Characters allowed are: 0-9 a-z A-Z

[Sparika]

Room name should be [0-9a-zA-Z]* and not [0-9a-zA-Z]*[a-zA-Z] @IdirB ;)

Actually, there is no need to check the room name format, just accept String instead of number only. ;)

fixed width a pattern accept just number or letters or numbers and letters and a name of room is required
