Create Games&Apps groups

[LuanRoger]

Implement games and apps groups. For this feature is required to have the shortcuts implemented.

• Use shortcuts to create groups.
• Use shortcuts to add games or apps to groups.
  • Shortcuts support #2
• Is not possible to have two identical app or game in a group.

The groups can be managed in the "Groups" section in My Library.

Manage groups

The group name will be clickable, and this will be used to manage the group.
Using a ContextMenu this actions need to be available:

• Rename groups.
• Reorder groups.
• Delete group.

[LuanRoger]

Group reordering has been made in tests but the experience is really bad:

• Focus problem.
• Bad design UI.
• Bugs occurs often.

For that reasons the Reorder groups feature will not be implemented for now.
