main.py: removed some of the testing code from mobile
bootstrap-small-cleaned.css:
 added different margin-lefts for the text according to screen size
hackerdojo.css:
 uncommented the smaller screen css so it now shows the three bars(although it wont open with js at the moment)
 made the join pop-in smaller
 added a different join button
 made the close button an x and an actual button
added a compiled bootstrap min js, so it is less to load and doesn't depend on another cdn
base.html:
 commented bootstrap js for now, is currently only used if the screen width is too small for the pop-down tab
main_page.html:
 used jquery from static/js instead of calling it from google (better implementation y/n?)
 added some more text to content of page
 maid the join popin look better
base_mobile.html:
 used the compiled bootstrap from static
 made google jquery load not async, because bootstrap depends on jquery to load first
