Merge tag 'v0.9.8' into develop

Changes to fix some account related problems like importing, hidden account usage.
 - disable returning rootAccount if no default account is found, due to this would just wind up to the user as using the wrong profile, and that is tougher to debug
 - renamed root account to root, so that if it is used, its easier to ask users what account its using
 - warnings clean up
 - on import ensure that the default profile exist, if it can detect what the user wants to use as the default, use that one, otherwise, create a new default one.
 - remove any stored urls, compondents to match against, username, and used text for root account, as it shouldn't be used in this manner
 - unit tests to demostrate differences in md5 algo uses, to prove that this version is correct.  rememebering that the difference is that it trims leading 0's
Null is default to 0.  Due to chrome edition using the string 'null' as a value in the xml, also check for that
