Display visual icons where is makes sense

The app in v0.3 is quite ugly... Adding some icons here and there could make it a bit prettier, and easier to understand.

For example :

• Icon to launch a "sync", instead of the strange symbol that nobody understands (i've had several people telling me they searched for a while before understanding how to sync / the purpose of that not-looking-like-a-sync-button thing)
• Icon for menu, exit, ...
• Icons in the list of entries : reading time (a clock ?), EPUB/HTML, ...
• Icons in the menu : "starred", "delete all data", ...

Here's a suggestion I got on Twitter : https://twitter.com/TcitWorld/status/831497139712692225

And here's how it renders in the app, for the sync button (I also made it a bit more square, with a touch-area a bit larger):

I have not commited anything yet -- will keep working on this (maybe in a few days, maybe next week, depending on the time I manage to assign to this)

Work in progress is on branch add-icons-here-and-there

Things that are quite OK: loading the icon from a PNG file, displaying the icon.
Thing that is not OK for now: the PNG icon file is re-created everytime the application starts => in the future, it should be re-created only when it doesn't exist or must be updated.

And here are a few more icons (in the header and in the global menu) :

And in the context menu :
