Minor deck editor fixes

Fixing Shortcuts; Fix #476

Speed up deck editor filtering

 * card: cache simpleName for each card
 * deck editor: remove double comparation of searched term with card
name when sorting

updated second string

Game created code improvements

Updated grammar based on #932

Added menu item to open custom image folder

Updated invalid username dlg

updated

+ No longer get "5hrs" and "5+ hrs" instead will be "4hrs" and "5+ hrs".
+ 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

Capitalized some text

Updated context menus

Restricted unreg usernames

Server was using message limit for commands

Needs to be tested on mac

Server was using getMaxMessageCountPerInterval over
getMaxCommandCountPerInterval.

Raised command limit from 10 to 20

+ added more separators
+ swapped some actions from lib menu (scry action now higher)
+ Added capital letters to words

Updated message limit from 10 -> 15

Can now only be made up of [a-z][A-Z][0-9][-_]

I have updated the `maxMessageCountPerInterval` from 10 to 15. This will
allow some faster play from exp users.

NOTE:
If you have an existing server and update to this version, you will need
to manually change the value in the ini file, or have no ini file to
begin with. Otherwise the old ini will load in 10.

When the list os sorted using another column, you don’t  need to
compare that column’s value with the searched term

Zone crash fix

Related to #808

When closing the app/game tab with a zone revealed the client will
crash. This was due to the zones not being deleted.
