LCC directory organization and inclusion of a helper script. 

The goal of this pull request is two fold:
1. Move all example files from the root project directory (.c, .lcc, and .pcf2) into their own examples directory. This make sit easier to maneuver around the various core project files and any potential helper scripts.
2. Add a helper script (lcc_bytecode_gen) that removes the need to remember a rather long and unclear set of commands for LCC to compile the appropriate bytecode (especially as there are multiple intermediate targets). A further compile defines that LCCDIR must be set to the local path in the script. It is also possible, in the future, for the script to rely on the LCCDIR environmental variable to be set, but given an already persnickity LCC compiler, it is probably best to keep it hard coded for now. Running the script with no arguments shows proper usage.
