Readme Updates

[Cheetham, Anastasia]

As part of our preparation for the release, we need to update the Readme file with a brief list of "What's New" for 1.3, as well as highlights of any known issues (i.e. bugs that didn't get resolved for this release).
    http://issues.fluidproject.org/browse/FLUID-3879

Justin has asked me to coordinate this, so I'll be pinging people individually for information, based on who seemed to work most on what, which seems to me to be:

Inline Edit: Mike
Progress: Justin (in Golam's stead)
Reorderer: Antranig
Pager: Harris
Uploader: Colin
Keyboard-a11y plug-in: I'll take this one
Framework: I can probably start this
Portal: I'll write this one
