Process for cleaning word content

1. Convert entities to characters excluding tags
2. Strip trailing spaces.
3. Find/Replace "\.\ +" with ". " to remove stupid period and double spaces.
4. Find/Replace "\n{3,}" with "\n\n" to remove places with multiple linebreaks, eg more than one.
5. Find/Replace "^&#?[A-Za-z0-9]+;\s" with "- " to make bullets from entities.

Sensible File Permissions

For Folders:

find ./ -type d -exec chmod 755 {} \;

For Files:

Both at Once:

find ./ -type d -exec chmod -v 755 {} \; && find ./ -type f -exec chmod -v 644 {} \;
