Should we check if two windows share the same name?

[craigdh, 2013/02/11 23:40:12]

Seems like that would be a common issue. Also what do the window handles look
like? If they're just integers I can see opaque collisions there as well.

[chrisgao (Use stgao instead), 2013/02/12 01:26:02]

Window handles look like: "1", "2", etc. for Linux; "12_1", "12_2", etc for Mac
and Windows.

Now also check collision between window name and window handle.

Add chrome/test/chromedriver/basic_types.h

Done.
