Pastebin.com integration.

A button added to the Debug tab to conveniently create a new paste from
the debug info on Pastebin.com. The API key in the **build.properties** file
should be replaced with a valid one. An API key can be obtained
automatically by creating an account on Pastebin.com.

Also some new localized strings are added:
SETTINGS_DEBUG_CREATEPASTE: *Send to Pastebin.com*
PASTEBIN_TITLE: *Pastebin.com*
PASTEBIN_TEXT: *Please include this URL in your feedback:*
PASTEBIN_LOADING: *Loading...*
