Fixes bug 2260.
Create 'pootle/assets' before building the static data.
Make MIN_SIMILARITY for fuzzy matching configurable.
Fixed for duplicated strings with placeables.
Changed singular strings to allow proper translation.

it to allow proper translations for those languages.
Cache table should be named 'pootlecache'.

Unit.submitted_by and Unit.commented_by fields are marked as Metadata for
