GUI: Add custom task icons

Previously, the task buttons used stock icons chosen to approximately
fit the task when displayed with the icon theme on my computers.  But
they don't fit so well in other themes, and sometimes no icon is shown
at all.

So, now they have their own icons, specifically designed for CrystFEL.
