Move Profile widget out of desktop-widgets

The reason for that is, even if profile widget is made with qpainter
and for that reason it should be a desktop widget, it's being used
on the mobile version because of a lack of QML plotting library that
is fast and reliable.

We discovered that it was faster just to encapsulate our Profile in
a QML class and call it directly.

+
+ This is a generically item and should be used as a base for others, I think...
