taskwarrior: 2.4.4 -> 2.5.0

Paste from the changelog:

There have been a lot of changes. Here are the highlights:

  * Improved command line parser: terminator -- handling, UUID
    recognition, DOM recognition, red-herring pairs (foo:bar), escaped
    slashes in patterns (/one\/two/), substitutions (/one\/two/one-two/),
    Unicode U+NNNN and \uNNNN, escaped entities (\n, \t etc) for use in
    descriptions/annotations, abbreviated day and month names, ISO-8601
    durations (PT4H, P1Y etc).

  * New virtual tags UDA, ORPHAN, PROJECT, PRIORITY, and LATEST.

  * Improved support for DOM references in filters task
    'due.year = 2015 and due.week > 20' list.

  * New configuration settings urgency.inherit, rule.color.merge,
    urgency.user.tag.next.coefficient, color.uda.<name>.none, sugar,
    report.<name>.sort:none, json.depends.array.

  * Improved urgency: the urgency.inherit setting propagates urgency
    along dependency chains.

  * Improved searching: more powerful regular expressions.

  * Improved attribute modifiers: is/isnt are now consistent exact
    match operator equivalents to ==/!==.

  * New command _unique, for generating unique lists of values, and
    will ultimately replace several helper commands.

  * New command commands, which lists commands and details about how
    they affect filters, GC, context, and syntax.

  * New verbosity tokens recur (feedback when a recurring task instance
    is created), unwait (for when a waiting task becomes visible).

  * Improved extensions: zsh completion, Fish shell completion, add-on
    scripts now online.

  * Improved documentation: help command, man pages, more online docs,
    negation ! operator, sample hook scripts.

  * Improved sync: GnuTLS now mandatory, so everyone has the sync
    command.

  * Improved JSON import/export support: free-format JSON, task arrays
    assumed (which makes import/export work with out-of-the-box parsers),
    dependencies optionally modeled as an array, UUIDs validated, tasks
    added/updated without duplication, import from STDIN using -.

  * Improved performance: less data is read from disk depending on the
    filter.

  * Improved diagnostics: duplicate dependency warnings, multi-task
    edit failures, changes to tasks without IDs, certificate file sizes.

  * Improved testing: migrated all Perl tests to Python, parallelized
    test suite, colorized output, detection of newly passing tests,
    Python 2.7 and 3 support, better debug output, Bash test library,
    stress test tool, no more disabled tests - everything runs, test
    coverage is now 87.3%.

  * Widespread code cleanup, removal of dead code, C++11 enhancements,
    improved portability, merged ISO-8601 and legacy durations, less
    code, happier developers.
