[temp commit] 1st try to optimize datedetector/datetemplate functionality (fix ambiguous resp. misleading date detection if several formats used in log resp. by format switch after restart of some services): * Misleading date patterns defined more precisely (using extended syntax %E[mdHMS] for exact two-digit match) * `filter.d/freeswitch.conf` - Optional prefixes (server, daemon, dual time) if systemd daemon logs used (gh-1548) - User part rewritten to accept IPv6 resp. domain after "@" (gh-1548) 8 years ago			`[INCLUDES]`

added possibility to specify more precise default date pattern: - `datepattern = {^LN-BEG}` - only line-begin anchored default patterns (matches date only at begin of line, or with max distance up to 2 non-alphanumeric characters from line-begin); - `datepattern = {*WD-BEG}` - only word-begin anchored default patterns; - `datepattern = ^prefix{DATE}suffix` - exact specified default patterns (using prefix and suffix); common filter configs gets a more precise, line-begin anchored (datepattern = {^LN-BEG}) resp. custom anchoring default date-patterns; 8 years ago			`datepattern = {^LN-BEG}`
