Merge lp:~carlos-mazieri/ubuntu-filemanager-app/samba-browsing-01 into lp:ubuntu-filemanager-app

[Carlos Jose Mazieri]

Class DirItemInfo which represents items being shown receives more attributes suitable for network like: DirItemInfo::isHost(), DirItemInfo::Browsable() and DirItemInfo::isSharedDir(); DirItemInfo::isShare() and DirItemInfo::isWorkgroup() are related to samba only.

This starts a series of MPs that provides samba browsing in the filemanager plugin.
There will be some samba-browsing-nn MPs until a samba-browsing-final from where it should be possible to browse a properly configured samba network by entering url "smb://" or "cifs://".

These changes provide browsing only, the development for samba Actions (copy/cut/pate, remove) will start next.

MPs from 01 to 03 are introduce new "Item Properties" and some refactoring to allow others network protocols be easily implemented.

Class DirItemInfo which represents items being shown receives more attributes suitable for network like: DirItemInfo::isHost(), DirItemInfo::Browsable() and DirItemInfo::isSharedDir(); DirItemInfo::isShare() and DirItemInfo::isWorkgroup() are related to samba only.

Please fix the few issues I inlined in comments.

review: Needs Fixing

[Carlos Jose Mazieri (carlos-mazieri)]

Thanks, I will fix that.

[lp:~carlos-mazieri/ubuntu-filemanager-app/samba-browsing-01]

387. By Carlos Jose Mazieri on 2015-03-16

Fixed DirItemInfo::removeExtraSlashes() using now QString::indexOf(QLatin1String(":/") to prevent common files using ':' in the names
Fixed documentation from DirItemInfo::fillFromStatBuf()
Expanded some if without space as "if(" to "if (" in class DirModel
