there was no reason to explicitly check whether to place a horizontal
next to another horizontal after all the other checks were done.

* Russian locale

* Russian locale. Plurals fix

eliminates flint and steel (aliased to mt_game fire:flint_and_steel)
eliminates fake_fire:fake_fire (aliased to mt_game fire:permanent_flame)

mt_game already provides a "fake" fire in the form of a "permanent flame", strike a coal block with flint/steel to get it.

modifies default ice block so that it can be "ignited" (ice fire on top) with mt_game flint/steel

Fire mod must be enabled. However, fire damage is NOT required.

just checks for creative mode/priv directly instead, as needed.

* add some translatable strings

* updated translations
add option --sort-by-file to updatepo.sh

* Updated de, pt, pt_BR translations
from pull requests #378 (Wuzzy) & #379 (afmachado)

pt.po and pt_BR.po are the same but pt.po is usable by any portuguese speaking people, not only brazilian ones

* improved french translation

(water is now blue like it used to be)

(they're too bright against the darker colors e.g. green)

use soft overlays for cover trim,

(get rid of redundant overlay polys)

before param2 coloring went in.
