Issue:
==============
N/A

What was done:
==============
* Optimized the way the `DebugPlugin` renders the tile grid by using
horizontal and vertical lines instead of rectangles for each tile.
* Added a few pre-calculated constants related to level size.
* Simplified `translate_transform_to_grid_space` code by using grid size
constants.
* Updated `bevy` to 0.13.2.
* Updated all dependencies to latest versions.
* Removed `lazy_static` dependency by replacing its usage with a Bevy
`Resource`.
* Removed unused `bevy` features.
