Add regex to --match-filter

This does not fully deprecate `--match-title`/`--reject-title`

while `--match-title` can often be checked from the flat playlist.

--match-filter FILTER Generic video filter. Any field (see
"OUTPUT TEMPLATE") can be compared with a
number or a quoted string using the
operators defined in "Filtering formats".
You can also simply specify a field to
match if the field is present and "!field"
to check if the field is not present.
Multiple filters can be checked using "&".
For example, to only match videos that are
not live, has a like count more than 100, a
dislike count less than 50 (or the dislike
number or a string using the operators
defined in "Filtering formats". You can
also simply specify a field to match if the
field is present and "!field" to check if
the field is not present. In addition,
Python style regular expression matching
can be done using "~=", and multiple
filters can be checked with "&". Use a "\"
to escape "&" or quotes if needed. Eg:
--match-filter "!is_live & like_count>?100
& description~=\'(?i)\bcats \& dogs\b\'"
matches only videos that are not live, has
a like count more than 100 (or the like
field is not available), and also has a
description that contains "python", use
--match-filter "!is_live & like_count>100 &
dislike_count<?50 & description*='python'"
description that contains the phrase "cats
& dogs" (ignoring case)
--no-match-filter Do not use generic video filter (default)
--no-playlist Download only the video, if the URL refers
