Chromium-MultiProfile-Prototype

Summary
=======
Implement a prototype of multiple profiles in Chrome by
utilizing the functionality of user-data-dir command line
flag that already exists.

A profile in this case is an umbrella for all user data
including cookies, history, bookmarks, settings, etc. Each
profile gives the user a separation of all these data
elements.

User Interface
==============
- Wrench > "New window in profile" menu item, with sub-menu items.
	This new menu item has sub menu items for each existing
	profile, for up to 9 profiles, and one more sub menu item
	to launch a window in a new profile. The 9 sub-menu items
	also have the accelerators like CTRL + SHIFT + 1, CTRL +
	SHIFT + 2, etc. If there are more than 9 profiles, we
	will also show an extra sub-menu item, "Other...".
- New Profile dialog box
	This dialog box is shown to the use when (s)he clicks
	Wrench > New window in profile > <New Profile>. It lets
	the user specify a profile name, and also shows a checkbox
	to create a desktop shortcut to launch Chrome in that profile.
- Choose profile dialog box
	This dialog box lets the user select a profile from a drop
	down to open a new window in. It also has an item <New Profile>
	in the drop down, selecting which will show the new profile
	dialog box mentioned above. CTRL + M shortcut also launches
	this dialog box.

Code Organization
=================
chrome\browser\user_data_dir_profile_manager.h/.cc:
	This class provides an abstraction of profiles on top of the user
	data dir command line flag.

chrome\browser\views\user_data_dir_new_profile_dialog.h/.cc
	New profile dialog box code.

chrome\browser\views\user_data_dir_profiles_dialog.h/.cc
	Choose profile dialog box code.
