Bug#609849: nixnote: switch to ITP for nixnote2

[YANG Boyuan <073plan@gmail.com>]

Control: retitle -1 ITP: nixnote2 -- open source evernote client
Control: owner -1 !

Hi,

The nevernote / nixnote upstream has dropped java implementation.
Instead, they began the development of nixnote2 and implemented in Qt / C++.

Upstream git repo can be found on GitHub [1].

I wrote to Vincent earlier and he told me that he is not intended to
package / maintain nixnote(2) anymore.

The new software can be packed easily but still need to be reviewed. I
will file the RFS when it is ready.

The intended package information shall now be:

* Package name    : nixnote2
  Version         : 2.0~beta8
  Upstream Author : Randy Baumgarte <randy@fbn.cx>
* URL             : http://nevernote.sourceforge.net/
* License         : GPL-2
  Programming Lang: C++
  Description     : open source evernote client


Thanks,
Boyuan
