Multi directories and fixed XSS vulnerability.

I did a little edition to this

- *Added multidirectory support*. Now you can explore all the directories after that file.
- *Added breadcrumbs*. I've also added breadcrumbs paths :smile: 
- *Edited home link*. Now it goes to the index of the file. After you explored everything, you can get back to the index.
- *Removed XSS vulnerability*. If you call a file "hi< b >\lol", (spaces because github allows HTML) HTML would be converted because it wasn't parsed. Now it is. :) 

Just a simply lines of codes more. I hope you like it :)
