- Rewrote js processing of uploading / editing: added ajax forms processing including file uploading
- Changed public functions to static: wpvp_return_bytes(), wpvp_max_upload_size()
- Moved video upload / edit html into the template files. Users can now overwrite these template files with their own in their template.
- Also added shell_exec back to video / thumb processing (it got incorrectly removed at some point).
