Local Storage for builds

[gw2princeps]

Changes / additions:

• Saved results are permanently shown now; maybe this brings more attention to this feature.
• A button to open the saved results manager was added
• The manager allows a number of things:
  • Saving a character to the local storage
  • downloading characters
  • copying characters to the clipboard
  • a nice overview over all the saved builds :))
  • Renaming a character to keep track of own builds more easily

This is ready in theory. One thing that is up for discussion is the handling of dual wielded weapons in the result tables. Since we can restore builds with a different option on dual/single wield, the table will bug out.

Hm. We could make the table always have 2 weapon rows and span them if you have a single weapon I guess. Looks kind of weird though. More advanced logic could do that if any build has 2 weapons maybe.
