v0.5.0

Warning: there is a bug in this version that means the database will not be created if the .tmsu directory does not exist. Please create the directory by hand (e.g. mkdir ~/.tmsu) until this is fixed.

Note: This release has some important changes, including the renaming of
some options, the introduction of local databases and a switch from absolute
to relative paths in the database. Please read the following release notes
carefully.

• The --untagged option on the 'files' and 'status' subcommands has been
  replaced by a new 'untagged' subcommand, which should be more intuitive.
• The --all option on the 'files', 'tags' and 'values' subcommands has been
  removed. These commands now list the full set of files/tags/values when run
  without arguments. For the 'tags' subcommand this replaces the previous
  behaviour of listing tags for the files in the working directory: use 'tmsu
  tags *' for approximately the previous behaviour.
• The 'repair' subcommand --pretend short option has changed from -p to -P (so
  that -p can be recycled for --path).
• The 'repair' subcommand's argument now specify paths to search for moved
  files and no longer limit how much of the database is repaired. A new --path
  argument is provided for reducing the repair to a portion of the database.
• A new --manual option on the 'repair' subcommand allows targetted repair of
  moved files or directories.
• The exclamation mark character (!) is no longer permitted within a tag or
  value name. Please rename tags using the 'rename' command. (Value names will
  need to be updated manually using the Sqlite3 tooling.)
• Added --colour option to the 'tags' subcommand to highlight implied tags.
• 'tag' subcommand will, by default, no longer explicitly apply tags that are
  already implied (unless the new --explicit option is specified).
• Added subcommand aliases, e.g. 'query' for 'files'.
• It is now possible to tag a broken symbolic link: instead of an error this
  will now be reported as a warning.
• It is now possible to remove tags with values via the VFS.
• 'tag' subcommand can tag multiple files with different tags by reading from
  standard input by passing an argument of '-'.
• TMSU will now automatically use a local database in .tmsu/db in working
  directory or any parent. The new 'init' subcommand allows a new local
  database to be initialized. See Switching Databases for detail.
• Paths are now stored relative to the .tmsu directory's parent rather than as
  absolute paths. This allows a branch of the filesystem to be moved around,
  shared or archived whilst preserving the tagging information. Existing
  absolute paths can be converted by running a manual repair: tmsu repair --manual / /
• Added 'config' subcommand to view and amend settings.
• The 'help' subcommand now wraps textual output to fit the terminal.
• Rudimentary Microsoft Windows support (no virtual filesystem yet).
• TMSU can now be built without the Makefile.
• Bug fixes.
