add more default shortcuts

[ebbit1q]

Short roundup of the initial problem

a lot of actions in the client don't start out with a keyboard combo, if we set more defaults people might ask about them less, and if they don't like them they're going to have to change them in the settings

What will change with this Pull Request?

replace the ctrl a look at top of library shortcut with ctrl shift n
use ctl a for draw arrow
replace ctrl shift b for toggle sideboard lock
use ctrl b for move card to bottom of library
replace ctrl shift m for mill cards.. with alt m
use ctrl shift l for start local game
add keyboard shortcuts for all 3 counter colors using , . / keys
use ctrl [ ] \ for the "other" counter
add ctrl = as an easy alternative to ctrl + for people without keypads
( on linux ctrl alt keypad + is a special key that is reserved in x
it produces the XF86_Next_VMode keyboard event which isn't bindable )
use alt u for toggling untapping
use alt l for peeking at cards
use ctrl alt u for unattaching cards
use alt n for set annotation
use alt y for milling one card
ctrl shift p opens the settings
alt f flips a card

this will be disruptive to players that have bound these keys to other things in the settings already as they will end up with duplicate shortcut entries, we hope that these people still remember that you can change them in the settings at any time

I'd also like a shortcut to open the settings, I like ctrl shift p but there are other options, not many apps have a shortcut for settings as far as I can see though
