changed order of methods in rambles_controller to reflect how they are displayed on the ramble show page
added in comment in map js to add in code for Foursquare and Yelp venue markers
added in show/hide and pagination JS for as-of-yet unbuilt shows section Noah intends to work on (songkick API, I think). Noted that some formatting issues with nav menu and ramble page had cropped up prior to any additions I made this evening. Was unsuccessful in determining root CSS issues.
Merge pull request #198 from gregburton/master

Major addition was putting in pagination and show/hide JS for eventual Songkick integration. (Noticed formatting issues with ramble page and nav bar [both on Heroku and locally] prior to these updates but was unable to fix them in a timely manner.)
