Reinstates hidden cards being hidden; fix #884

Fixed accidental +/- of counters when using middle click menu

Refactored code and made lines cleaner

Before:

After:

Reworked a bit mentions/tags support in chat view; fix #791

tray icon is now hidden and then removed

Fixed order of the counters

Previously if you middle click on a counter (life/mana) and then click
away, depending on the button clicked, the counter would +/-.

I have added a fix to make sure the mouse is over the counter to change
it.

Previously had - numbers at the top and + at the bottom.
This feels like it makes more sense.

I noticed that sometimes I would have lots of icons in the sys tray. I
would have to mouse over them to make then be removed. This also happens
with some other programs too. I have added some code to hide() the sys
icon when the client is close, it seems to be helping with the issue.
Hard to reproduce, might also only be a windows issue.

Fix double popup on delete pics

Set cmc to 0 if not set; fix #669

Misc Startup fixes

Avoid error “QIODevice::read: device not open”

The check was inverted. LoadStatus::Ok = 0, so only when
db->loadCardDatabase() returns 0 we know the card database path is
correct
