[Tails-dev] Please review and merge feature/5711-liferea-per…

Hi,

Please review and merge into devel the liferea persistence preset.

This actually consists of three parts:

* installing lifrerea 1.10 from wheezy-backports and starting it
  through usewithtor
  - Branch: tails:feature/7154-install-liferea-above-1.10.3
  - Ticket: Install liferea > 1.10.3
    (https://labs.riseup.net/code/issues/7154)

* implementing a liferea persistence preset
  - Branch:
    persistence-setup:feature/6403-implement-liferea-persistence-preset
  - Ticket: Implement Liferea persistence preset in Tails wheezy
    (https://labs.riseup.net/code/issues/6403)

* documentation and integration
  - Branch: tails:feature/5711-liferea-persistence-preset
  - Ticket: Persistence preset: Liferea
    (https://labs.riseup.net/code/issues/5711)

The last branch also includes a persistence-preset patch to easily test
the feature. The patch should be dropped once a version of
persistence-setup including it reaches devel.

So merging this branch consists of:

- merging tails:feature/5711-liferea-persistence-preset into tails devel
(this includes tails:feature/7154-install-liferea-above-1.10.3)
- merging
persistence-setup:feature/6403-implement-liferea-persistence-preset
into persistence-setup master

Thanks by advance
