Upload location is now platform dependent 

win32 defaults to %APPDATA%/Cura/uploads
macos defaults to ~/Library/Application Support/Cura/uploads (I hope, can't test it...)
linux defaults to ~/.cura/uploads

Server now also checks if file to be uploaded or deleted ends on .gcode and makes filename secure before doing anything on the filesystem

Also added favicon ;) and some bla to the README.md

###Packaging
To package Cura into application bundle simply do `python setup.py py2app`. Resulting bundle is self-contained -- it includes Python and all needed packages.
WebUI
=====
This fork of Cura includes a WebUI for remote printing via the browser. It depends on the Python module "flask" and
its dependencies "werkzeug", "jinja2" and "itsdangerous", so you'll need those in order to run the WebUI. A simple
`pip install -r requirements.txt` or `pip install flask` should take care of that.
Once installed, you can startup the WebUI instead of the regular Cura UI via the command-line option `--web` or `-w`. The
web interface will then be available on port 5000. If you want to change that (or the IP address the server binds to,
which currently is `0.0.0.0`), please take a look at the source code of `Cura/webui/__init__.py`.
