Move all imports to have "readthedocs" at the top level.

[ericholscher]

This is something we should have done a long time ago,
as it matches Django's recommended layout since 1.4.

This allows us to remove the path hacking of adding the readthedocs subdir
to the PYTHONPATH on execution.

All changes were automated,
except for a few small hand-made changes,
which are the non-automated commits here.

Only other things changed:

• manage.py moved to top-level directory
• PYTHONPATH hacking removing from manage.py
• Prepended readthedocs to all imports

This is the script run:

import os

for app in os.listdir('readthedocs'):
    for dir in ['readthedocs']: # Useful for updating imports on dependent source

        if '__' in app or '.' in app:
            continue

        cmd = "find %s -type f -name '*.py' -exec perl -pi -w -e 's/^(\s+)?from %s/$1from readthedocs.%s/g' {} +" % (dir,app, app)
        print cmd
        os.system(cmd)

        cmd = "find %s -type f -name '*.py' -exec perl -pi -w -e 's/^(\s+)?import %s/$1import readthedocs.%s/g' {} +" % (dir,app, app)
        print cmd
        os.system(cmd)

        cmd = "find %s -type f -name '*.py' -exec perl -pi -w -e \"s|include\('%s|include\('readthedocs.%s|g\" {} +" % (dir,app, app)
        print cmd
        os.system(cmd)

        cmd = "find %s -type f -name '*.py' -exec perl -pi -w -e \"s/'%s.views/'readthedocs.%s.views/g\" {} +" % (dir, app, app)
        print cmd
        os.system(cmd)

        cmd = "find %s -type f -name '*.py' -exec perl -pi -w -e \"s/\@mock.patch\('%s/\@mock.patch\('readthedocs.%s/g\" {} +" % (dir, app, app)
        print cmd
        os.system(cmd)
