Patch by Michael Schwingen that

Browse Source 
- adds support for the Altium universal JTAG cable
 - adds support for "wiggler2" cable (basically a wiggler with added LED, documentation coming soon)
 - adds LED support. The LED is turned on during data transfer - works fine on Altium and wiggler2.
 - adds PORT_EXIT pattern that is written to port when exiting, in order to turn off power on cables that get their power from parallel port data lines
 - move port writes (with the system-specific ifdefs) to one central function

- increased image cache size to 2KB (might require more adaptive cache handling, e.g. LRU)
