Fresh taskmgr doc for review

[Mike Massonnet]

Hi,

I wrote a short user documentation for the task manager and since my
english is not native I had like to receive some reviewers. The
documentation is available here:

Kind Regards

PS: I'm not sure where the best place is to send such requests,
xfce-i18n sounds like a good space not sure what others think about
it.
