Alpha Hotfix Release 0.3.1

This is a hotfix for 0.3.0 that addresses the following:

• Fixed an issue where changing fonts preserved the original font's bounding boxes, causing the new font characters to appear broken.
• Fixed an issue with certain fonts having characters extend beyond the bounds of their glyphs. Glyph sizes have been amended to fit the full character size.
  

Changes from 0.3.0:

• Added a new parameter to font.set, as well as a new font.isSquare function. If set to true, this will set the width of glyphs equal to their height.
• Added a new function glyphs.size, to retrieve the size of a glyph.
• Removed unnecessary values from data::Uniform.
