The initial commit of this change was incorrectly reverted by be445eb.
English spelling corrections English/strings.po
dialog      -> dialogue
analog      -> analogue

A dialogue box (GUI - Yes/No/Informational or otherwise) contains dialogue, and as such should be correctly spelt, this project has a en_US strings.po of which this spelling would be correct, but not here).
"dialog" has not become an accepted form in English like "program" has instead of "programme" for use in computing terms.

analogue, the in use of opposite of digital, should be spelt -logue at the end.
(the spelling analog is American / en_US).

Once merges are made with Transifex, en_US can be correctly localised.
