Adjusted borders of rarities slightly.
Fixed a bug relating to shrinking mana costs in magic-future-textless.
Added option to left align artist and copyright in magic-old styles, as seen in Tempest.
Changed all magic-new, magic-future, and magic-planeshifted styles to use ModMatrix for p/t, increased font size 1 point, raised p/t 1 pixel, added "shrink-overflow".

Added a bunch of missing byte-order marks.

I have made it so that it is possible to access extra card fields through the script as many, many templates are suffering for no good 
reason as a result of them not being scriptable. I understand that the gamme shouldn't be allowed to rely on them, but the styles 
should, and as such, they should definitely be accessible from scripting.

Updated creature type lists in accordance w/ Oracle update.
Shrank textbox font size for magic-future.
Fixed new "colored multicolor land name" option in futureshifts.

Added new styling option to replicate "Murmuring Bosk" frame from Morningtide.

Keyword polish.
Various other maintenances.
Added "magic-mana-small-grey" as colorless mana font.
Removed "colorless mana" styling choice when applicable.

Updated expected_locale_keys

Adjusted dependancies.

Fixed: direction:vertical was putting characters on the next line, causing multi-char symbols to render incorrectly

Added larger masks for magic-new-planeswalkers to stop errors.

Fixed: positioning of stretched + rotated text

Altered creature type lists (they still don't really work right).
Fixed an error in champion keyword; still no championing multiple cards.

 Now all C++ files need to #include <util/prec.hpp>
 That is why all .cpp files are touched by this commit

Many changes to installers and update checking:
     - the window is now called PackagesWindow, in a new source file
     - update checking is now independent from the PackagesWindow. For update checking only a list of package versions are needed (vector<PackageDependency>). This is much less information to download at each startup.
     - the list of available packages is now a list of available Installers, since an installer can contain multiple packages.
     - moved the logic of dependency checking etc. to data/installer
     - moved the actual installation to util/io/package_manager
     - moved directory iteration/creation logic to util/file_utils
     - added PackageDirectory: the local and global package directory now have their own object (was part of PackageManager)
     - added PackageVersion: for detecting if a package has been modified after it was installed.
     - added PackageDescription: description/header of a package. Basicly the same as what Packaged provides.
     - added DownloadableInstaller: where to find an insaller, what does it contain?
     - added InstallablePackage: brining it all together: installer, package, status, action.

Current status: the insaller is currently broken in a few places, more on that soon.

 - Some refactoring of the other field types
