Update v1.02.1

This is the first update I've completed since the minor changes after the 7DRL challenge. Most of that time was spent on other projects though, so this update is rather small.

The following updates have been included:

• Improved rendering time of maps
• Changed symbol for player characters so the @ is always the currently controlled character (making it easier for color-blind players)
• Added a look command!
• Began adding more detailed inventory interface and commands
• Miscellaneous bug fixes

The next round of changes will involve adding equipment, ranged attacks, thrown weapons, and UI updates to display character stats related to combat. The plan is to include traps that also involve thrown items, melee weapons, and ranged attacks since the traps tend to use some of the same routines as the regular characters. I could also add enemies that use equipment. The plan is to have this finished in one or two weeks; the most difficult thing will be UI changes to choose a target, and then hit the first target in the created line.

Once equipment and items are working as I originally intended, the next step is to improve the dungeon generation algorithms. In particular, the hunger and thirst mechanics are not balanced well, and it's common to get a dungeon floor with mostly empty rooms (rather boring). It's also common to see doors in the middle of a room for some reason, so I'd like to fix that. There's already the functionality for secret doors, and locked doors opened by pressure plates (that can also trigger a trap), but the dungeon generator can't use them yet because of how it determines where a door goes. So that change will be the next major update that, hopefully, will start to increase the challenge and interesting situations in the game. Ideally, this will occur in mid-June.
