Tabs fine tuning

[bradleyrichter]

Test Plan:

Confirm styling and alignments changes are OK on windows 7, 8, 10.

Here's a shot from Windows 10

[bsclifton]

Windows 7 at 150% DPI

And lastly, here's Windows 8. Looks and feels consistent across the board 😄

@bsclifton thanks for the check...

It looks like the lock icon is moving up, and appears to be larger. Do you have a separate windows adjustment for it?

[bsclifton]

@bradleyrichter I don't see any Windows specific styles being applied. Lock shows as 16px (it's the FontAwesome face w/ class "fa-lock")

Here's a closer up shot. It does seem the URL could be centered better

[bsclifton]

Here's where the margin comes from (on Windows) that pushes the text in the input down:

browser-laptop/less/navigationBar.less

Line 731 in f62306a

margin: 2px 0 0 3px;

Setting it to have 0 margin on top seems to fix the issue (although, I suspect it may break Mac):

[bsclifton]

@bradleyrichter if you want to resolve the conflict, I think this is good for merge 😄

The issue I pointed out above is already captured with #4814

Please post a follow up labeled with release/non blocking to track, i can be tracked in 0.12.6 for now.
