Simple changes
Better queue (less innefficient and tried-to-be-beautiful-and-complicated-and-simple-but-failed)
Better selector.contains()
Merge branch 'transform' of github.com:RenatoGeh/deadfall into transform
Added not unselecting until mouse release.
Merge branch 'dev' of https://github.com/RenatoGeh/deadfall into dev
Fixed queue:pop not returning.
move_to and bullet

moved move_to to character, beginning of shooting
Tables for each kind of body

Also, a useful iterate method that let's you iterate over all of them in
one for.
Bullets disappear when out of screen

Still much to change
Bullets are now unregistered depending on the camera's translation and scale.
Added rotation to bodies. Added base.transform.

Changelog:
 1. base.transform:
  - Utility 'static' module for useful transformation operations.
  - Inspired by Java's AffineTransform's beauty and wondrous curves.
  - For a list of TODO functions for transform see TODO section.
  - Supposed to have as much documentation as possible (since it's a
    tricky area with more math than usually).
  - Called statically, that is: base.transform.rotate(...).
 2. Rotation:
  - Uses base.transform.
  - base.transform.rotate:
   i. Accepts a body, anchor point (optional) and a draw function with its
   passing arguments.
   ii. Anchor points are, if not passed, the center of the given body's
   bounds.
   iii. Drawing is done by receiving a function and parameters and then
   calling it in between push and pop stack functions.
   iv. Will work on multiple draws later on.
   v. Optimized as much as possible.
  - Both selector's selection marks (body outlines) as well as characters
    are rotated at this time.
  - Bullets need not be rotated for now, since they're circles.

Issues and Bugs:
 - None.

TO DO:
 - List of base.transform possible functions:
  a. shear (hey, why not?)
  b. translate
  c. scale
  d. identity (just like AffineTransform)
  e. MOAR AWESONESS
- Make ALL bodies "subclasses" rotate.
- Body, by default, rotate?
- Multiple draw functions passed on base.transform.rotate.
