can't override I18n translations

[krtschmr]

i copy all values and throw them into my en.yml.

no change will ever work.

somehow i try to debug the gem, when i start my application and check the I18n.load_paths ice_cube isn't in there, so as soon i call ice_cube, the I18n initializer of ice_cube is called and append his own paths.

for that reason, I18n will allways look at the latest occurence, which is always ice_cubes default en.yml

this seems to be a bad approach
