Add FreEPOC Lua port

[cezdro]

While there is a newer port, I couldn't find a precompiled version. Precompiled Lua 5.1.4 port is available at the following addresses:

• lua5opl
• lua5opx
• lua5cpp
• lua5lib

Cool. These are all Freepoc—not a name I've thought of in a little while. I'll reach out to them and see about explicitly indexing their content for the software index.
