[JENKINS-27058] Clarify that remoteFS can be relative if you know what y...

[JENKINS-16284] catch unexpected launcher error

don't call this local variable absolute as it maybe relative... it will be absolute when we are finished mind!

Integrated a newer version of remoting & args4j

[FIXED JENKINS-27436] <form> elements can’t be nested

- Ignoring all the other callables in this class that are missing a serialVersionUID

- of course drive mappings are user scoped and can change from user session to user session, so calling them absolute is a bit of a joke... none the less, for our purposes they are absolute enough

Instead of hard-coding the list, do this through @Extension(ordinal=...) mechanism.
This way, other plugins can add default columns in places that they control.
