Fixed jar and updated some images.

Images were missing from the jar.
Merge change from DF's branch.

Prevented possibility of making new texture each frame for map overview.

Allowed holding the 2 key to face a direction but not move in that
direction when using the movement keys.
Updated readme.
Merged some changes from DF's branch.

Started implementing an on-screen numpad for touch-screen compatibility.
Fixed issue.

Player can no longer spawn in a fully enclosed space with a chest on
their head, instead there must be a space to the left for the chest.
Various changes and compiled jar.

Game version is now alpha 4. Added two new potion images, added
invisibility potion, added some background music on a loop, allowed
skeletons to have effects, gave arrows and leech balls a max flight
time, made leech balls despawn on being blocked from moving, changed
rendering to account for invisible things (needs fixing).

add less ugly loading bar
Sync skeleton transitionTime with movementTimer
