Add Multi Segment LCD

Feel free to modify any chunks of code you want and ask questions about anything you wish.

This PR adds a segmented display to Wiremod. It has a complex tree-based UI for combining segments which get memory mapped to 8-bit bits in the memory of the display.

There are three types of segments:

• Segment - beveled rectangle of configurable dimensions
• Text - single segment corresponding to the entire string of text
• Matrix - an assortment of segments arranged in a grid of specified size

Along with two types of combinations:

• Group - arranges the segments in memory in order of appearance
• Union - places the segments in the same spot in memory

As well as two empty layout nodes:

• Offset - acts like a bunch of invisible segments
• Align - aligns the memory to some multiple of a provided number of bits

Press right click in the tree view to add new nodes.
