Upload files to server. Now works awful. Needs a lot work.
Quickfix of an incorrect decision
Started adding AJAX file uploading mechanism. Found it on StackOverflow.
Tried to write user part. Function which is called in case of success. Doesn't work.
Added Jquery File Upload library.
Added popup to the page. Simple one.
File upload WORKS. It is crude, but uploading works. I changed settings.py, now they are saved into textum/media/RTF.
Cleaned views.py and urls.py a bit; file is submitted after being uploaded.
Replaced input file field with button.
Cleaned textedit.html from old comments a bit + minor edits to pop-up block.
Pop-up is almost finished. Maybe I should add progress bar. For some reason, Quit button doesn't work.
Fix quit button bug.
Get server respone after file is uploaded.
Task #8.
Merge branch 'upload-files' into convertor
