Fix pthread compile errors on Linux

Resolve all compiler warnings

Improved Linux/BSD section in the usermanual.

Fix #34

This is @mcallahan's patch — see #35. I had to apply this diff by hand,
because both `git` and `patch` refused to apply it and I didn't know
how to resolve that. Consequently, there might be an error.

Deck Load Mods and Movable Tabs

decklist - Right aligned the regex check

Changes:
Deck Load - Default to all types *.*
Decklist - Strip "|edition" from .dec formats that include a pipe and
the edition after the card name
Tab_Supervisor - Make tabs movable (able to rearrange tabs)

Repeatly download text spoiler until a valid XML document is received

Added setting to enable/disable notifications

When something happens, the taskbar icon lights up/the dock icon
bounces. This can be annoying, so here is a setting to disable that.

Made Ctrl-V importer work more robust.

Added a UI option to play all nonlands to the stack instead of the battlefield

"The price tag feature currently has two bugs.
1. The final price that a card ends up with is the one in the last set
alphabetically, instead of the one from the set with the lowest price.
2. Black Lotus Project sometimes gets in prices for cards from Masters
Edition, for some reason. This set only exists in Magic the Gathering:
Online, i.e., not physically, and should not be considered. This might
be considered a BLP bug and not a Cockatrice bug.

This patch fixes those two bugs. I also changed the price value to be
based on BLP's "price" value instead of the "average" value. Seems more
logical."
