Allow Open Browser keyword to pass capabilities also for local browsers

[drobota]

Sometimes it could be useful to allow capabilities be passed also to local browsers. The current implementation of the Open Browser only passes the capabilities to the Selenium side only when remote_url argument is used.

I do not think there is a real reason other than no one has submitted a fix for it and there is a workaround.
@aaltat identified a workaround in #139. See also #342.
Here is the historical reason:
The ability to pass in capabilities to the __init__ of local webdrivers was not originally part of Selenium 2. For example, IE did not get this feature until Mar 4, 2013.

Considering the frequency of users being confused by this quirk and posting to SO or the user group, I think this should be fixed.

There has not been activity for this issue for long time and we are planning to close the old issues if they are not anymore valid ones. If you feel that this is still valid issue, could you send an update. If update is not received in a month, we will assume that this is not anymore an issues and we will close this issue.
