v1.0.2

Just a minor update. Mainly to make some under-the-hood changes to the way heap allocation and garbage collection works.

Change list:

• Under-the-hood changes to heap management and garbage collection.
• String literals now evaluate correctly in the debugger.
  • Data block literals now also evaluate in the debugger.
• New hex function converts a data block to a string.
• makemap will now accept a 1D array (useful when importing some map formats).
• Added maptilewidth and maptileheight to get the tile width and height of a tilemap.
• Windows applications, if launched from the console, now output log and error messages to the console.
