Merge pull request #78 from allenxwang/cp

Add capability to stop individual server list refresh and make thread pool size dynamically configurable.
[Gradle Release Plugin] - new version commit:  '0.3.11'.
Added JUnit to verify encoded query string handling.
Remove pitfall code in URI reconstruction; fix userinfo handling.

* newURI was always getting overwritten under normal circumstances
  (any time there was a / or ? or similar) so isURIEncoded is not
  necessary. Use of getQuery is dangerous, but the value was being
  thrown away. This commit helps ensure it will not be used in the
  future.
* getUserInfo is replaced with getRawUserInfo to prevent premature
  decoding of separators such as ":". This should be the only behavioral
  change.
