[net.micro] 6809 instructions

I have always thought that motorola missed a great opportunity with the 6809
instruction names.  There are 5 registers which can be loaded with a general
effective address, the stack/index pointers and the program counter.  The index
pointer loads are named  LEAX, LEAY, LEAU, etc for Load Effective Address to x.
For consistency the jump instruction would \naturally/ come out as:

    LEAP
