[MD settings] allow unicode nbsp in i18n behavior strings

This CL allows for the unicode non-breaking space '\u00a0' to appear in
translations. Such spaces appear in the French translation file 1600+
times, for example.

Tested the issue on Mac 10.12.5 using chrome dev version #61.0.3124.4 and on Win-10 using chrome dev version #61.0.3124.10 as per comment #0. 
Observed that in both OS-Mac and OS-Win, "Ouvrez le Chrome Webstore" appeared as expected in chrome://settings.

Note: Testing in Ubuntu 14.04, was not feasible as the issue need to be tested on a profile that does not have any theme, whereas in this particular OS by default classic or GTK theme is present in any profile as in the attached screenshot.

Attached screen shots for reference.

dschuyler@ - Could you please confirm if the issue is related to OS-Linux also.

Thanks...!!

As a heads-up. I'm working on a replacement CL for this issue. The fix above didn't 100% fix it (as described in  Issue 731289 ): The above fix only replaced the *first* nbsp in the string. The new CL is almost the same fix, but addresses *all* nbsp in the string.

re #15, The string shown in the bug description is not used on Linux (The use of the string is in an 'if' that tests to be sure the code is not running on Linux prior to using the string - so that's fairly solid). I'm not currently aware of a French string on Linux that is dynamic and contains a nbsp (non-dynamic strings, which are most of the UI strings, don't have an issue with embedded nbsp).

On ChromeOS, we've found that the nbsp can appear in the theme setting (as mentioned in this bug already); and in the Display Settings where it shows the resolution of the screen (e.g. 1024 x 768). This is also the reason for the update fix (which should be available shortly).

[MD settings] use regex to replace all nbsp

This CL allows for the unicode non-breaking space '\u00a0' to appear in
translations. This is an improvement (replacement) on CL 2926573003
which only replace the first occurrence. This CL will replace all of the
nbsp in the string.

The CL in comment #19 is corrected fix.

I've re-added the Merge-Request-60 and removed the Merge-Approved-60 for the purpose of asking for approval on comment #19 above.

Thanks for the quick fix. Please let us know when the corrected fix (#19) is tested and verified in canary/dev. We are aiming for an M59 re-spin on Monday 6/12 and since this is marked as releaseblock-stable, we'll need to get the fix merged before Sunday 5PM pacific to make it in release candidate.

It's been tested from top-of-tree on a developer build. I'm having some difficulty building a local m-59 branch to verify (in general, not specific to this issue).

Keen. I've been able to build m-59 locally and see: the original issue, the partial fix from CL at #7, and the full fix from CL at #19.

Thanks for checking/verifying - please confirm if this a safe merge overall? 

i say there's basically no risk of merging Dave's CL to M59

thanks - approving merge to M59. 

This bug requires manual review: M60 has already been promoted to the beta branch, so this requires manual review
