Use self contained ssh agent/config #1573
Description
conflicts can occur (mostly on Windows), with multiple SSH installs or configurations. this can prevent SparkleShare from working entirely. examples are #1559 and #1558, but there are more. we don't want to mess with people's existing installs.
no idea how to go about this yet, this issue is just for tracking.
a ssh config file in the SparkleShare install folder with hardcoded keys could be an option.
