Crafting fixes, and more

[zenorogue]

This mostly improves the crafting command, but there are also 3 fixes not directly related to crafting.

Crafting:

• a new item category, RAW_MATERIAL, is added.
• Fixed a crash when no item to create is selected.
• Removed the confusing askForEqualLumps when tailoring (its purpose seemed be to merge lumps, but you can merge lumps anyway, using a special command for that).
• Disabled the need for sewing thread. Needless complexity for now, at least until actual "sewing thread" item is added.
• Set page length of the main crafting menu to 11 -- all did not fit on my screen.
• The "inspect item materials" now shows the volumes of materials in an item.
• For items in the RAW_MATERIAL category, volume is always shown.
• After selecting an item to craft, a text screen is displayed, explaining all the available crafting options for that item.

Other fixes:

• Fixed the crash when pressing '^'.
• Fixed the number of pages shown in some lists.
• You can now dip things into ocean. This can be used to create bottles of brine which can be then helpful to extinguish fires.
• ShowAdventureInfoAlt did not redraw the map so it worked rather weird.
