Update to 0.5.0.

Release 0.5.0
-------------

The dependency of Perl and HTML::Tokenizer module have been replaced with
libiconv and PCRE for significantly lower system footprint. Perl was previously
used for parsing video titles and cleaning them up.

configure no longer supports --enable-sigwinch. The support is now compiled
into the program automatically if signal.h is found and defines SIGWINCH.

tests/ have been rewritten in C++.

Other notable changes:

  Removed options:
  --title
    - obsoleted by --filename-format since 0.4.1 
  --cclass, --no-cclass
    - obsoleted by --regexp and --find-all (below)

  New options:
  -r, --regexp
    - Defines the regular expression that can be used to "filter"
      video titles before they are used for filenames

  -g, --find-all
    - Used together with the above to repeat the matching to find
      all occurences, similar to Perl's /g option

  Example:
    cclive -gr "(\w|\s)" URL
