Issue #1958582: by aadityawalawalkar, thorsten: fixes a typo in the page callback for the info page.

Main javascript file sets the margins for each line number to the same as the element of the line it numbers. Pretty sneaky sis.

Cleaned up some of the settings. Got block formats working properly which opens up a world of styles. Currently I have to use what I feel is too much markup to achieve this, will look into using CSS columns for browsers that support it and then falling back to this method.

Removed whitespace on lines 56, 73, 97 and 127. Removed a dpm() call that was left behind. Removed empty line at end of file.
