Launcher3 : checkItemPlacement fixes

This patchset addresses two bugs :

1) Incorrect casting of key causes mismatches
2) On hotseat items 2 and above, the occupied hashmap is populated
with the CONTAINER_HOTSEAT key, however if its a new item and its required
cell is not already been taken, the code falls through to the workspace checks.
Make sure hotseat items are treated separately.

Allow some customization in Launcher3

This patch allows a user to customize:
- Grid with and height
- Default homescreen position
- Visibility of the search bar

These items can be configured in a new Activity, which replaces the system
settings as target of the icon in overview mode.

Shortcomings:
- Bounds for cols, rows and defaultWorkspace may need to be adjusted
- When one of the values changes, the Launcher activity gets recreated
  completely.
- When searchbar is hidden, you also lose the visible hints for the
  remove/appInfo drop targets.
