doc/go1.7.html: update documentation regarding compress/flate

Document the following:
* That the algorithmic changes are still compliant with RFC 1951. I remember
people having questions regarding this issue, and it would be good to re-assure
them that it is still standards compliant.
* io.EOF can now be returned early (c27efce66bce7534dbb357ac1779bbc08395b267)
* Use the term "decompress" when referred to as an action. The term "uncompressed"
or "decompressed" are both valid as ways to represent the current state of the data.
