Fix console spaming by debug function on mod checking for global variable to exist.
Make duplicate warning checks file and line specific
Adjust the values of dirs1 and dirs2 so that rotate_and_place orients textures correctly

According to doc/lua_api.txt if paramtype2 == "facedir" the two least significant bits of parm2 orient the texture around the axis. For dirs1 (looking at a wall) these would be 0, 1, 2, 3 and for dirs2 (looking at the ceiling) 2, 1, 0, 3

EMF_USE_MIP_MAPS was introduced in Irrlicht 1.8, don't use in 1.7.3 or below

This is not optimal as it will cause minor graphical glitches for
Irrlicht 1.7 users, but at least it fixes the build.
Wield: always obey anisotropic_filter setting, not just for hi res textures

Improve Lua API documentation

Changes:
  * Add extra documentation for remove_item.

    This isn't as silly as it sounds: iterate a list containing items with
    unique metadata each, and remove_item the first one you find, placing
    into a different - fine, except the remove will invariably remove the
    wrong one, leading to items being duplicated and others destroyed.

    Arguably it's a bug, and Inventory::removeItem should actually remove
    the item you tell it to. (i.e. if the passed ItemStack has metadata,
    match it). But it seems reasonable to just document the behaviour
    more clearly.

 * Improve string_to_pos documentation.
 * Clarify dig_node documentation (return value).
 * Better on_step documentation.
 * get_nodemeta -> get_meta.
 * Other minor fixes.
