Use iptables trough iptc, enables rootless operation

Reviving my PR #41 and
polishing it up a bit for easier usage

…rQueueWrapper

Refactor connection.py to use namedtuples instead of classes

Move utility functions to get app path and cmdline into proc.py
get_pid_by_connection now only gets pid by connection data

Move Application into connection.py, this didn't really do much anyway
and had some overlap with connection

Move more things into ui subpackage that should not belong in daemon

As an added bonus this also gives a nice little decrease in memory usage

Rule performance fixes

Improve code styling and performance in proc.py

Split ui into separate subpackage

This decreases memory usage because of Python using a shared
dictionary for all instances of Rule

Previously was O(N), now only O(N) in worst case

Move LinuxDesktopParser into ui subpackage, it does not belong in the
Opensnitch core

Add ICMP support

Add unique constrain to sqlite db (fixes #70)

Dont show dialog if connection got permanent rule

Currently the UI will show dialog if the connection got a permanent rule
after the connection was queued.
This fixes this behaviour.

We are also having an issue where the QComboBox won't get reset to Once
after being set.

Fix packet blocking behaviour while UI is open (fixes #40)

There are a few non-obvious reasons why this commit is so big:

The PyQt mainloop must run in main thread.. This was not particularly
easy since the packet callbacks were running in the main thread.

Because of the PyQt running in the main thread thing NetFilterQueue had
to be wrapped up in a thread.

The packet callback is now dispatched to a thread if user has to be
prompted.
Packets are sent over a queue to the ui thread.

SQLite connection must be called from the same thread it was created
in. Thats why all the calls are wrapped up in a lock and create a new
connection. This is not ideal but I would say it's good enough for now.

resizing should work now

Minor ui improvements in resizing

Fix for the resizing window and text issue
