Bug 30733: Fix string context lost due to being in two parts

Due to conditions. Things like "Edit batch" need to be keept in one
strings.

Also removed some capitalization because it wasn't needed and wasn't
consistend with <title> and <h1> which had now capitalization.

Also fixed patron edit-batch.tt and edit-layout.tt because they were
incomplete in regard to their label counterparts. They had the condition
on description and batch_id but weren't displaying anything different
between the two cases.
