Add a nav item for "Featured Songs"

[bryanbraun]

Gives the sidebar two "song navigation" options: "Recent songs" and "Featured songs".

The Navigation UI should set a pattern for more song navigation options in the future (favorite songs? popular songs?)

Featured songs will just be a list of my favorite submissions I've seen (and a link to the submitter). Here are some ideas:

• My Neighbor Totoro by @BryanEBraun
• Merry Go Round of Life by @hzjxhnxuu
• Columns by @fuzzballfox
• Super Mario Land - Birabuto Kingdom by @BryanEBraun
• Umi No Mieru Machi by @BryanEBraun
• Super Mario Bros - Underwater Theme by @BryanEBraun
• Untitled by @VctorCastilloR
• Super Mario Bros Theme by @BryanEBraun
• Moolight Densetdsu (Sailor Moon) by naonotweet1
• Memory (Undertale) by @HoneyLily15
• Zelda's Lullaby by @BryanEBraun
• Gusty Garden Galaxy by @StevenBraun0
• Luma by @StevenBraun0
• Winnie the Pooh theme by @BryanEBraun
• There's Always Tomorrow by @BryanEBraun
• Theme from Up by @StevenBraun0
• Do you want to build a Snowman by @BryanEBraun
• Pokemon Center by @BryanEBraun
• Pallet Town by @BryanEBraun
• Reprise from "Spirited Away" by @hbraun25

Also: I can have a link at the bottom of the list saying "Want to add your song? Email me."

Update: I'm going to increase the sidebar width to make room for two "tabs" in a tabbed interface. This allows for more semantic navigation and headings (which would eventually be useful for search engines). Plus, I felt like more content-browsing space would become a necessity, and the select-box option would look a little janky there.

If we end up getting a bunch more tabs, it would be nice if it ended up wokring like a priority-plus nav.
