Emerge activity

There was some (really) few minor fixes. We don't support python 2 any more.

The main feature is that we've switched to Qt5. There are also some minor improvements, such as 'smoothness' configuration and several fixes for the neverending moving target matplolib, along with some general fixes/cleanup.

• the png file was created even in "qt mode". It is no more.
• slightly changed the convolution function to get smoother graphs

As usual (see main page/wiki), to get the software you can either clone the mercurial repository or download a release tarball from the 'File' tab.

Despite minor bug fixes, this new interface is the main point for this release. Also i've made it slightly more formal: instead of cloning the mercurial repository, you can now also download a tarball from the "File" tab upthere.

EmergeActivity is a small script based on python and matplotlib that creates an image displaying emerge successes over time. See the wiki for more information and screenshots.
It now has been tested/used for one year and is released as such.

If you now what source control and 'mercurial' are, you can clone the repository from the repository, else you can download the script here : EmergeActivity.py
