Merge lp:~nataliabidart/ubuntuone-control-panel/folders-tweaks into lp:ubuntuone-control-panel

[Natalia Bidart]

- Needed to split test_gui in two files due to lint warning 'too many lines in module'.
- Cleanly show the specilal folder of purchased music (LP: #720650).
- 'User' icon for cloud folders list is now 'avatar-default' (LP: #706034).
