#352 [1.23.2 - beta] Falsely changed project after window lose focus

[Fellype]

An unmodified project is interpreted as modified if the SciDAVis window losses focus or a new project is started.
To reproduce just start SciDAVis and perform one of the following operations:
- minimize and maximize the window;
- switch to another program and return to SciDAVis (type Alt + TAB, for e. g.);
- open a new project (type Ctrl + N)

-> You will see that the 'save icon' is available or you will be asked to save the project if you try co close SciDAVis.

Tested on Slackware 14.2, 64 bits; built against Qt4 and Python 2.
