merge revisions 1980 and 1981 from trunk to branch-1_7
put some code from the huge section_init to 2 functions - parse_section_url does the exact opposite of make_section_in_url - parse_well_known_params_url does the exact opposite of add_well_known_params_in_url maintenance on categories also invalidates the user cache git-svn-id: http://piwigo.org/svn/branches/branch-1_7@1982 68402e56-0260-453c-a942-63ccdbb3a9ee
