zh_TW.po: fix translation of 'previous' term

Previously this term is translated as "previous one", however it
actually applies to all previous versions.  This commit corrects the
translation and also applies to other same-term-but-different-tranlation
strings for unification.

zh_TW.po: update translation of "Help"

Currently, the menu named "Help" is directly translated as "幫助"(may read
as verb/noun in Chinese).  I "patched" it to "尋求幫助(Seeking for help)"
hoping it to be more sensible for users who are really need to find some
more help on using git-cola.

This "patch" is indeed "this particular translator's own preference and
convention" rather than "convention of general zh_TW localization
community", so ignore it if you want to keep safe :-).

diff: replace "Section" references with "Diff Region"

The term "Section" is ambiguous to new users.
Use "Diff Region" since that is more explicit.

po: update i18n for "Diff Region" change

This does not actually update the translations.  Replace the term
"Section" with "Diff Region" since the spirit of the phrase should be
the same in the current translations.  This does not touch zh_TW since
Vdragon will probably update it.
