v0.5.0

Enhancements:

• Added the ability to let TinyMCE automatically add opt-in content classes (.table on <table>s, .blockquote on <blockquote>s. By default this is enabled, but it can be disabled via plugin settings in case of third-party component conflicts.
• Updated the "Formats" dropdown in the WYSIWYG editor to exclude .table and .blockquote classes when automatic opt-in class insertion is enabled.
• Added a new labelledby shortcode attribute for [tab-pane].
• Upgraded packages

Bug fixes:

• Fixed non-functional option_{$option->option_name} filters. Plugin options are now properly formatted when returned via get_option().
• Replaced break with continue in ATHENA_SC_TinyMCE_Config::get_format_options() to allow null format options to be passed in without breaking all other format options.
