Reduce space requirements by squashing opcode + flags + value into 32 bits.
This has been achieved by reducing opcode's width from 16 to 8 bits. This is fine as there's 172 opcodes still available at present so plenty of room for expansion. Flags have been reduced from 16 to 10 bits wide and currently have 8 bits unused. This leaves 14 bits available for the opcode-specific value. No opcode needs all 14 bits at present.
Inherit is now a global flag rather than a pre-defined value. This saves looking at the value field at all when styles are inherited and generally reduces complexity.
