There is now a new file: "custom.inc" that can allow the user to make
site specific overrides, keep sql passwords out of the main ini file,
etc...
This is completely optional and not required. The file may even be
safely deleted if wanted.

Also some typo fixing in the README file.

Removed user-edited files so they do not get overwritten when updating
the scripts.
The user-edited files are now contained in the user-file.tar.gz archive.
Once decompressed they will not be effected by future "git pull"
operations.

Made changes to how the scripts find the included files, the whole thing
can now just live in one directory, allowing for easier future updates.

Added http-meshmap.conf file to plug in to apache configs. This allows
the <WEBROOT>/meshmap directory to live virtually anywhere on the
filesystem.

Updated README file to reflect these new instructions.
