0.15.5.0

• [feature] Version of each injected package is now listed after name for pipx list --include-injected
• [feature] --suffix option for install to allow multiple versions of same tool to be installed (#445)
• [feature] ensurepath now also ensures that pip user binary path containing pipx itself is in user's PATH if pipx was installed using pip install --user.
• Change metadata recorded from version-specified app install to allow upgrades in future. Adds pipx dependency on packaging package.
• pipx now parses package specification before install. It removes (with warning) the --editable install option for any package specification that is not a local path. It also removes (with warning) any environment markers.
• Disabled animation when we cannot determine terminal size or if the number of columns is too small. (Fixes #444)
• [bugfix] Prevent python error in case where package has no pipx metadata and advise user how to fix.
• [bugfix] For pipx install, fixed failure to install if user has PIP_USER=1 or user=true in pip.conf. (#110)
• [bugfix] Requiring userpath v1.4.1 or later so ensure Windows bug is fixed for ensurepath (#437)
• [feature] pipx logs its own version in verbose mode (#423)
