Fix errors from #1689 localization

@Adaptivity
- STR_EPOCH_WALLWITHDOORLOCKED_DESC string was missing
- I see no reason STR_EPOCH_PLOTDEED_ACTION was renamed to a less
descriptive name, and it was missing the German translation from the old
one, so I changed it back
- These build actions in fn_selfActions are for vanilla building. They
shouldn't be in the Epoch package. I renamed them and submitted them to
vanilla too.
