Clean up and organize JS files

[Igor Santos]

The orgiinal theme came with a lot of unused JS. Many things are packaged in the theme.js file and related scripts, but they were copied all over several blade templates.

• [x] That JS file should be cleaned up
• [x] unused plugins should be removed
• [o] JS inside templates should be cleaned up and, if possible, unified
• [ ] the final scripts should be compressed into one file, taking advantage of Gulp and CDNs for library files whenever possible
