We have to iterate all layers on commands that modify the whole
sprite. It doesn't matter if the layer is "browsable" (e.g. it's
expanded or collapsed).
If the Timeline has an active selected range of layers and the user
creates a new layer group, the selected layers will be be grouped as
children of the new layer 'group'.
This is a first step to include the current selected range of layers
and frames inside the doc::Site structure. So in the future we'll not need
to know about the Timeline in commands that handle those ranges.
Changes:
* Add KeyboardShortcutsCommand and window
* Add SelectAccelerator window
* Replace modules/gui.cpp functions with app::KeyboardShortcuts and
app::Key with the logic to load/save/handle keyboard shortcuts
* Change ui::Accelerator concept: now it represent just one keyboard
shortcut, not a set of shortcuts
* Remove ui::Accelerator from ui::MenuItem, now the key is associated
in app::AppMenuItem and it's a app::Key
* Add Command::onGetFriendlyName() to get a user friendly name of the
command depending on its parameters
- Add HAVE_CONFIG_H wrapper to #include "config.h"
