Token dialog: disable progressive loading

Save deck editor's database view columns state

CardDb: be permissive when loading xmls

Prevent PTColumn from being the last column shown.

Rework some parts of the card database

Updated ClientID Functionality

Yay!  Figured out how to do this in VS2015!

Moved the updated hashing function out of the settingscache and into the
remoteclient and privatized the function for proper use.

ClientID is now generated on startup and stored in settings cache.  Then
upon connect there is a new SrvClientID generated from the ClientID +
servername being connected to

Remove "Ghost" Toolbar

I'm working on a theme and realized we have a toolbar that used to be used for price, which we no longer display. I removed the code (and the unused price code action) as we weren't using either.

P/T column is really narrow. It should go before Card Type, so Card Type can expand into the remaining space.

Improves #1671, assuming I got this correct.

Untested!
