Scripts runner sɣur TrianguloY

Provides a button that, when pressed, will show a list to create, delete, run and edit scripts. It also provides a button to export the current scripts to a json, and another to import scripts. [Don't run untrusted scripts obtained from unkown sources!]

Note: this is my first published extension, and it has currently very basic functionality. I'll consider upgrading it in the future, criticism is welcomed.

Permissions:
<all_urls>: Permission needed to run scripts inside iframes generated dinamically (unfortunately the 'activeTab' permission don't allow this). No scripts are run in any background tab or anywhere else.
storage: Permission used to save and retrieve the scripts. Otherwise when closing/reopening the extension they would be gone.
clipboardRead: The export/import feature uses the clipboard for convenience. Will consider removing this to manual copy/paste.
webNavigation: The permission needed to run scripts in the current tab/iframe.
