Bumping ibrowse library to version 1.6.2 (latest).
It has a few important bug fixes and new features, such as, for example: 1) fixes https requests not going via the proxy; 2) added SSL support for direct connections; 3) fixes to URL parsing; 4) added option headers_as_is git-svn-id: https://svn.apache.org/repos/asf/couchdb/trunk@985730 13f79535-47bb-0310-9956-ffa450edef68
