Masteries & Runes copy & paste

Add a "Copy" and "Paste" button in mastery and rune pages.

Copy places a hexidecimal/binary text string representative of mastery or rune page in clipboard, paste retrieves such a string and "pastes" it to your currently selected page.

This would allow players to easily move pages around.

Web pages (like MobaFire) could also implement similar "Copy Page" buttons/links which would make it easy to literally copy/paste pages you'd like to use without having to click them in one by one all the time.

Also, please add "Move Left (<<)" and "Move Right (>>)" buttons to the Runes and Masteries pages, to allow players to organize their runes/masteries pages. The above mentioned code alterations would make this significantly easier to implement, to boot.
