improve UX between automaterial and buildingplan

solves the confusing behavior when both automaterial and buildingplan
are enabled for constructions. the two plugins now communicate with each
other over the Lua layer to negotiate consistent behavior.

if neither plugin is enabled, the standard DF UI acts as normal

if automaterial is enabled but buildingplan is not, then automaterial
behavior is unchanged.

if buildingplan is enabled and automaterial is not then behavior is
the same as other buildings with buildingplan (no material selection
screen, screen stays on building placement screen after placement).
this commit fixes a bug, though, where buildingplan would only lay
down a single tile of contruction instead of a solid block when a
block is requested.

if both plugins are enabled but buildingplan is not enabled for the
building type then automaterial is unchanged from previous behavior,
execpt for an additional header showing the separation between
automaterial hotkeys and buildingplan hotkeys.

finally, if both plugins are enabled and buildingplan is enabled for the
building type then buildingplan behavior prevails, but the box select and
hollow designations features of automaterial are still usable and
useful. the 'Auto Mat-select', 'Reselect Type', and "Open Placement"
automaterial hotkeys are hidden in the UI and ignored in the feed. This
is because buildingplan takes over material selection, so 'Auto
Mat-select' doesn't make sense. Buildingplan also already stays on the
placement screen after placement, so 'Reselect Type' is not necessary.
And all buildingplan-placed buildings have relaxed placement
restrictions (e.g. they can be built in mid-air) so 'Open Placement' is
also not necessary. The missing options are replaced with blank lines so
the vertical alignment of all other options stays constant.

we also remove a few extra lua_pop() calls that are made superfluous by
the StackUnwinder.
