Since 79e095fd8a609b71937057034ff5801c13180137,
modern js experience is mostly controlled by feature
detection instead of user agent sniffing.
This broke the Echo nojs browser tests and the
mwext-mw-selenium job is now failing on ALL Echo patches.
This change introduces a user agent string that is
both still considered a nojs browser by RL and a
desktop browser by MF.

The new oouified echo popup makes the tests invalid; this commit
rewrites those tests.
Also by doing this commit we are upgrading to Selenium 1.4.
