Add journal and preliminary strings for crafting

The journal is now functional. Preliminary strings are added for the
1.8.7 crafting system, but it is disabled for now.

I've messaged @marceldev89 (ziellos2k) and @AlbyBDPK on the DayZ forums
to ask permission to use fn_updateCraftUI, player_checkRecipe and
player_craftItemGUI. Are you guys okay with us including these in DayZ
Epoch 1.0.6?
