[ChromeOS] Enable hovering effect for "not configured" network.

[ChromeOS] Enable hovering effect for "not configured" network.

Also fixed a "connecting" attribute not properly set problem.

BUG=chromium-os:15596
TEST=Verify fix for chromium-ls:15596. i.e. Blue strip shows up on hovering "not configured" networks. Also "connecting" network now will show up in a lighter blue (compared with "connected" networks) box with no hovering and no buttons.

Thanks for pointing out that we need to handle "connecting" networks.

CL updated:
- Fixed "connecting" not properly set problem and now "connecting" network will
show up in a lighter blue box;
- Removed css rules for "connecting" network about height, padding etc. Those
seems to be needed by inline password entering and not needed right now.

Please take another look.
