Update dictem to 1.0.0.
Based on maintainer update request by PR 39892.

Major changes in 1.0.0:

   - Running dictem-initialize everytime your network/internet is up
     (if case you have no permanent connection to Internet,
     e.g. dial-up, adsl etc.) is a bit annoying. To avoid this dictem
     is (re)initialized (if needed) automatically from
     dictem-select-strategy and dictem-select-database functions.  As
     a result, running dictem-initialize in .emacs becomes unnecessary

   - New function (dictem-reinitialize-err) added

   - Minor fix in dictem-initialize-databases-alist function.  Now it
     returns error data in case of failure, not nil.
     (just like dictem-initialize-strategies-alist)
