Add New Theme Monokai Dark Soda and Fix Menu Bug

Add new theme Monokai Dark Soda inspired by a Sublime Text 2 theme by [mrlundis](https://github.com/mrlundis/Monokai-Dark-Soda.tmTheme) that I really enjoyed and missed.

Also fixed a replacement bug where not all hyphens were being replaced if more than one was used.
