transmission*: update to 4.0.0

With two patches provided by Onno van der Linden.

## 4.0.0 beta 1

- Resource Efficiency - Use less memory, fewer CPU cycles
- Better Community - Pull requests welcomed and used
- Code Modernization - Rewritten in C++

### New Features

- Support for using BitTorrent v2 torrents and hybrid torrents. (Support for \ 
_creating_ v2 and hybrid torrents is slated for an upcoming release.)
- Users can now set "default" trackers that can be used to announce \ 
all public torrents.
- Newly-added seeds can start immediately and verify pieces on demand, instead \ 
of needing a full verify before seeding can begin.
- Added an option to omit potentially-identifying information (e.g. User-Agent \ 
and date created) when creating new torrents.
- The Web client has been rewritten and now supports mobile use.
- When creating new torrents, users can now specify the piece size.
- IPv6 blocklists are now supported.
- Beginning with 4.0.0-beta.1, Transmission releases now use semver versioning.
- Dozens of other new features -- too many to list here! We've been working on \ 
this for a year!

### Qt Client

### GTK Client
