Make this library PCL compliant

Quick survey result:

We need to beat 24 compile errors before achieving this port.

We need PCL compliant REST API agent library to achieve this.

Candidates:

• https://github.com/advancedrei/PortableRest/
  • Supports Xamarin
  • Still maintained
• https://github.com/danielcrenna/hammock/
  • Sunset (fork w/ WinRT support is https://github.com/Yortw/hammock/ )
  • Need more work to make it Xamarin-ready

So, replacing network API access by PortableRest seems great.

Was a longer way than I expected, but managed to make things 80% done. support-PCL branch compiles and 6 tests out of 15 run successfully.

[muojp]

Now stage 1 is completed via #2 and stage 2 w/ full feature tests just started.

[muojp]

Test status

14 ran, 11 succeeded, 3 failed.

Unimplemented parts

• membership management
• uploading attachments

[muojp]

16 is a great step forward (no more failing tests).
