Updated ui
-script insertion fully working
-script return uses predefined OmniScriptValue object for placeholders
-script templates under options displays with spacing for better visibility that does not interfere with running the code

Most functionality is implemented though not fully built out for all scenarios
-email templates properly check for associated placeholder scripts and run them and replace the placeholder with script returned values
-addon templates -> copy to clipboard currently (quick copy)
-scripts limited to single return values(one-liners) as multiple lines of code cause the first value returned to always be undefined breaking the associated template
-browser message handling added in some capacity to handle running scripts on current webpage(testing)
-primarily updating to this version to ensure browser compatibility for background messaging before trying something more complex with the dynamic scripts.

-Options button added
-Testing updates to add-on
