Emulate the hold touch behavior on non touch device by clicking the right key
ButtonTable: do not add vertical separator to the layout because the focus
manager can't traverse them. Add check to make disabled button non-clickable.
* [device][kindle4] add fake event to kindle4
* modify focusmanager to allow for more complex layout
The focusmanager now naviguate the layout by avoiding nil value
instead of relying on table lenght. It should be completely backward
compatible
* add Dpad naviguation to the touchmenu
* fix crash because virtualkeyboard on non touch device
the kindle4NT has no keyboard nor touch, the fix open the virtual
keyboard so koreader dont crash but it's not useable
* Enable device with keys to use the touchmenu
* Don't get stuck in reader progress statistics plugin
* [underlinecontainer] Fix and remove unused function
References #1898.
* Fix crash with keyboard navigation of onHold buttontables
Would crash when encountering a separator or when the number
of buttons in a row changes.
* Reset previous selected item on new buttontable
This should finish the work to make all globals to local variables.
That allows LuaJIT to properly compile things by interning the
references to the relevant parts (rather than looking up globals
all the time which stops a trace).
