More functionality in the "Help" menu.
Redo resource system (1/2). Yes, some icons are missing.
Redo resource system (2/2) -- supports icon themes now.
This also fixes the stuff the previous commit broke. And everything
looks a lot nicer now :)
Don't double-connect.
Fixes to strings and signals/slots connections.
Fix (probably not possible) memory leak.
I dunno what this will help, but it's bad practice not to have it
anyways.
Warnings, warnings everywhere.
Most of them caused by GCC options. They probably wouldn't cause a
problem, but someone must've enabled those warnings for a reason.
Refactor LogWidgets to use UIs.
Rename RenderWindow -> RenderWidget and add "render to main window"
functionality.
Delete RenderWidget when we're done with it.
Rewrite the GameList code. Grid view is missing, will be back soon.
Update about dialog.
Update file extension list.
Disable the AddFolder action as well as Open and Refresh.
