Naming Convention for Text Primitives

[Magnus Forsberg]

... going to fix only the tile or also the text primitives as I reuse them...

I've now had a look into all the text prims. I found four I want to fix. The letters B, O, T and Y.
B and T have some internal unmatched primitives and T-junctions.
O and Y have a bad corner, that might affect the design you're working on.

I'll fix the overlaps and gaps in the tile, and also the letters mentioned.
I see no need to recycle the rest of the letter prims only to replace 2-4disc with 2-4chrd.
