help Gridcoin: run the dev version of the wallet please

It would help Gridcoin a lot when you run the dev version of the wallet.

You can find the code repository for it and the commits here.

See here how to run/install it. Thanks!

Keep in mind: 

• It is a dev version, so don't use it yet on your live wallet... If you have a spare PC, run it there first.
• Check out existing bugs/ideas or report new ones in the bugtracker.

If you are interested in what to look at/test first:

@ravonn posted here recent changes:

... here's what has happened in the dev branch since the last hangout.

• C++11 has been enabled which will allow us to use more modern code constructs
• Bug from dark theme support has been fixed: this and this
• Slight memory reduction using more efficient CPID storage
• Lossless recompression of existing resources
• Removed unreferenced resources (obsolete images)
• Splash text color is now black, aka readable
• Fix gradient warning when launching from the console
• Unit tests have been resurrected

Also a shoutout to everyone who helps the development by providing test data, doing code reviews and leaving feedback on github.
