+ Refactored into an else-if with a single return.
+ removed comments
+ removed code from namespace and added to class

Removed check

When searching for a card the line edit will not be empty, so this check
is not needed. The performance when the line edit IS empty will take a
slight hit, but you really want additional performance when searching,
not when the line edit is empty.

Removing will increase performance.

Simple name searching on by default

Previously would try to match the card name, if nothing is found, then
we would try again with the simple name.

I have now made it only the simple name version. We do not need to
perform the first check. Should help a little with performance.

Relates to #964. We want to give a the correct reason for failed logins
and display the reason why.

Updated server side user name check

Added "-" to allowed names
