* PHP: UF_Field_Richtext will no longer add blank lines when displaying multiple paragraphs.
* PHP: UF_Field_Separator does no longer use automatically generated labels. This way translations can work.
* PHP: New tabs' text can be translated too now, missing textdomain added.
* PHP: Options pages can now reside under other Ultimate Fields pages.
* PHP: uf_extend is now called on plugins_loaded. This way all that is extended will have access to more hooks, including widgets_init.
* JS: New repeater elements can be toggled by using the arrow.
* Translations: Fixed the path in uf-bg_BG.po
