JDK 7 Milestone 3: Release Team approval now required for M3

[Mark Reinhold]

Lana and Alan pointed out that my message is confusing, if not
self-contradictory, so allow me to clarify:

    All changes intended for builds 58 through 60
    require Release Team approval.

Please ignore any phrases in my previous message that mention
specific times of day in specific timezones.

I'll update the status page (http://openjdk.java.net/projects/jdk7)
in a moment.
