Bootloader PIC version

v1.04

milestone version - now waits 10 seconds on powerup for serial char, if so it 
downloads new program through serial port.  If not it jumps to previously 
downloaded program.

See _pic serial test 04.zip for mainser.hex, the file used to test this.

v1.05

Works beautifully.

v2.06

added EEPROM support

v2.07

works - but second EEPROM byte after writing to program memory is always wrong!

v2.08

passed all tests
