v4.5.0

Features

• Many components for the Buildable Stick System - Arcade Edition --- pieces to create a control enclosure for the Qanba
  2009 base! These pieces live in extras/bss-ae/ but do use some parts from the base project; check that subdir's
  README.
• Created a Sega 2P 11 button layout, basically following the curve of the fourth column and adding a fifth, plus one
  extra button
• More decorative plates, this time square ones for an NES-styled project.

Improvements

• Button layout positions for Sega 2P and directional arc layouts have been parameterized.
• The decorative plates for the directional arc + W and Sega 2P 9 layout have been split into two files, since there was
  no reason to keep them as one with multiple pieces anymore.
• Tweaks to the horizontal stripes in order to get them to print better.
• Renamed "Sega 2P plus one" to Sega 2P 9, following the pattern of the 11 layout.

Miscellaneous

• Renaming of extended side pieces to fit the front/back idiom.
• Cleanups to the demos.
