1) Assets window: adds clear list context menu item.
2) Assets window: allow deleting multiple selected items.
3) Assets window: fix list view cursor key navigation.
4) Backend: correctly blend transparent background cursor cells with canvas character cells.
5) Backend: correctly determine cell size & set font size.
6) Backend: correctly unmask cursor.
7) Backend: disable font anti-aliasing on Windows.
8) Backend: render transparent background cells as RGBA #303030FF.
9) Canvas window: adds <F1> accelerator for `View melp?' menu item.
10) Canvas window: implement {dockable,floating} toolbars w/ wx' AUI framework.
11) Canvas window: separate tools toolbar from edit commands toolbar & dock both on right-hand side alongside each other.
12) Flip horizontally tool: flip characters, including some Unicode symbols.
13) Flip vertically tool: flip additional Unicode symbols.
14) Text tool: don't process keyboard events w/ either of <{Alt,AltGr,Ctrl}> modifiers.
