Fuzzy translations

[Hannie Dumoleyn]

Although the documentation string freeze will be on March 16th, I 
already want to start translating untranslated strings here: [1].

In this version (Zesty) I noticed that there are untranslated strings 
which were translated in a previous version. Example: string 
#112=untranslated, but it is translated in 16.04 version.

Before I start merging these versions manually and upload them to 
Launchpad, I would like to know if there is another way to get fuzzy 
translations in a newer version based on an older one.
