Tool for maintenance of .po and .pot files

Normally, the i18n-related files contain for each translatable string a

reference to all the source code locations where this string is found. This

meta data is useful for translators to assess how strings are used, but is not

relevant for normal development nor for running Kallithea. Such meta data, or

derived data like kallithea.pot, will inherently be outdated, and create

unnecessary churn and repository growth, making it harder to spot actual and

important changes.
