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...
