Namespaced Filters & Dried up the code

Instead of repeating the networks over and over again, I think defining
them once would be best here. Now it's easier to add more in later on
(or remove some).

Also this helps to add filters on later ( I'll work on that very very
soon ).

This is not the best solution right now. Instead of using Variable
variables, we should use extract() on array in the template parts, but
that's something for another day.
Ran TidyPHP
Dynamic Option Checking

Instead of checking all the options manually, we can check if the key is in Tipsy options.
Dynamic Option checking in Admin Area

As well.
Modified the rendering of networks and more

Networks now can be rendered by a custom function that user can define in functions.php on the theme side. Useful for Theme Developers.

Also Added the option to remove some options if they aren't supported, that way if the options aren't there, user won't be fooled later on. For example if the theme doesn't support Tooltips, but the user has set tooltips on.
