Refactor / clean up code

[JuanMenendezBuitrago]

After all this time developing and adapting the disconnect.me code to suit our needs, some original source code has become unnecessary. In order to avoid too much memory use and to ease understanding of current source code and debugging, some refactoring / clean up tasks should be done.

For instance, port.js is not needed if we're only offering the extension for Chrome and content.js holds code that looks like does nothing in particular. There's the following for clause

for (var i=0; i < 0; i++){
...
}

that obviously, never gets executed (in fact this piece of code has been modified in disconect.me).

Having stopped working with Chango also has made pieces of source code not needed.

Also, I find the writing of variables in upper-case very misleading since generally speaking, one would expect this practice to be used on constant values only... but this is just a mater of personal taste. Maybe we could just leave in upper-case those variables accessible from every javascript file in the extension, like being in a extension scope.

Anyhow, some clean up must be done.

ok. Be careful not deleting things that are used or may be used in the future. For instance Chango logic is not used at this point but may be later.

Check with me on a case by cae if you have doubts
