Move GridMapEditor to bottom panel

find another solution to hide/show the transform gizmo (using set_state)

fix the selection_level_instance not applying transform from the node

correct the rotation of the selection after duplicating or moving a block

fix giant cube on start up

remove few unnecessary lines of code

re-introduce clear rotation in the setting/tool menu

added icons and change the size_slider with zoom_widget

make the paint and select tool work

start adding tools in toolbar

make the selection cursor

but there is a bug with the Q and E shortcuts

fix cursor not updating when button toggled

when button are part of a group, they send the signal `toggled` rather than `pressed`
we also made sure that the transform is updated correctly after the cursor update

add cursors

update cursors and move more actions to toolbar

add clear and change fill shortcut
