Location change.

Since I changed the location of the project, change the locations stated for
some sample files in the sample LEM file.
Generalization---plain files in a lem file.

I need to distinguish between files that have the Lua ZIP extentions, and
those that do not.  So add a flag to zipw.file() and zipw.dir() to indicate
the extension is required.
Feature---the ability to store regular files.

They will appear under _FILES/, a "virtual" top level directory where none-Lua
module/application files go.
Clarify calls to zipw.file() and zipw.dir()

The last parameter is a flag denoting a Lua module vs. a regular file.
Move Lua modules to the _MODULES/ namespace in the LEM file.
Adjust output of this tool.

Just print the file names for stuff under _FILES/, not all the
information I was displaying.
Save stuff under _FILES for possible opening.
Make sure we get the proper version of LPeg.
mz.crc() can now take a NULL pointer.  It won't change the CRC.
Fix output of zipf.

It was off by one space.
Make the license "MIT/X11" the same as "MIT".
A script to place LuaRocks into a LEM file.

Yup.  It's ugly.  It's pretty hardcoded.  This is still a "proof-of-concept"
at this stage.  Not until I know exactly what is required, this will be messy.
And now a script to run LuaRocks from a LEM file.

Again, ugly, hard coded, blah blah blah.  It does work though.
Update the README with the new layout.
Add license info.
Add some documentation.

It's some.  Probably not enough.  But it's some.
