Version 1.14.2

When running ./configure: If update-mime-database and/or update-desktop-database is not found, ./configure completes without error. However, UPDATE_MIME_DATABASE and/or UPDATE_DESKTOP_DATABASE will be set to "no", which is not a valid command. "make install" will throw an error in the data/mime directory:

make[4]: Entering directory `/tmp/planner-0.14.2/data/mime'
no "/usr/share/mime"
/bin/sh: line 1: no: command not found
make[4]: *** [install-data-hook] Error 127
make[4]: Leaving directory `/tmp/planner-0.14.2/data/mime'

Proposed solution:

- AM_CONDITIONAL(ENABLE_UPDATE_MIMEDB, test x$enable_update_mimedb = xyes)
+ AM_CONDITIONAL(ENABLE_UPDATE_MIMEDB, test "$enable_update_mimed" = "yes" -a "$UPDATE_MIME_DATABASE" != "no" -a "$UPDATE_DESKTOP_DATABASE" != "no" )
