Update locations templates and locale files are stored Installing on a new ubuntu 22.04 venv at /tmp/roundup, I found the locale and template files installed under /tmp/roundup2/lib/python3.10/site-packages/usr/local/share which was unexpected. /tmp/roundup2/lib/python3.10/site-packages/tmp/roundup2/share would be expected. Why sys.prefix (/tmp/roundup2) was not being used but sys.base_prefix (/usr) and 'local' were added in I have no idea. In any case, updated admin and i18n code to find the files in this location. Suggested building a venv for installation with commands in installation.txt. Removed search for templates top level directory. Was used for the old location of the tracker templates pre-2009 when they were moved under share/roundup/templates. left print statemts for debugging directory search in admin templates. They are disabled by a variable set to False. At some point will add pragma's to admin to set debugging and other options see issue 2551103.
