New additions to PolygonFormatEditor menu

[Dr-HyperCake]

I have updated the PolygonFormatEditor menu to add new features, improve existing ones, and clean up the code.

• Reordered field options to be more logical. Options are ordered by the size of the data type they correspond to, which also happens to prioritise the options most commonly used in Smash.
• Added a new field for vertex color type. (Replaces a checkbox.)
• Added a new field for UV type.
• Added a new field for face type.
  • Added conversions between triangles and triangle strips. The conversion to triangle strips currently doesn't have an algorithm to make proper strips, so it simply converts the triangles directly into individual strips.
