v0.8

• Added a new option: notify_on_all_messages_in_buffers_that_match. It is a comma-separated list of regex patterns of buffers for which you want to receive notifications on all messages that appear in them.
• Added a new option: notify_on_messages_that_match. It is a comma-separated list of regex patterns for which you want to receive notifications for any message whose body matches the given regular expression. Contributed by @bbugyi200 in #12.
• Added a new default tag into ignore_messages_tagged_with: notify_none (see #10).
• Print an error message when notify-send fails. From a user's viewpoint, this is better than showing the complete backtrace (see #11).
• Replaced the word plugin with script in README and source files as technically, weechat-notify-send is a script, not a plugin (see #8).
• Dropped support for Python 3.3 (it is EOL). When using Python 3, require at least Python 3.4.
