Demo version 0.3.0

Additions:

- Enemy intents now respond to mouse hover and display an explanation window.
- Added three new characters to the character selection screen. They are unavailable in the demo but are shown there regardless.

Adjustments:

- All necklaces are now marked as tier IV items and they specify that they are special items.
- Rebalanced enemy AI for multiple attacks. Enemies are now able to do attacks below 3 damage.
- Slightly shortened some tutorial texts.
- Adjusted character status bar hover texts to introduce the stats first and then present the formulas last.

Bugfixes:

- Fixed a bug with the save system forgetting to load character data in the main menu.
- (Player bug report) Fixed a bug where the enemy dodge bar could show an incorrect preview before the player moves tiles on the grid.
- Fixed a bug where the game thought it was being played on a widescreen resolution in windowed mode.
- Fixed jumping text in the text window that is shown at the beginning of the tutorial and every run.
- Fixed a lag spike when opening the map for the first time.
