Add "lite" mode

Set unified_inventory_lite = true in minetest.conf to enable.

This mode reduces the feature-set of the mod as follows:

* no bags
* no waypoints,
* no home/go-home buttons,
* no set-day/-night buttons,
* smaller creative/craft guide inventory pages (4x6 instead of 8x10)
* fewer paging buttons
* smaller search field
* move "Result: foo" to below the crafting guide grid.
* Move main "tab" buttons to the right, below the search and paging buttons.
* Made "tab" buttons able to use to 2 rows if necessary (max 8 buttons)
