added mobot project and the df bot

mobots/README.please

+
+
+this is my little mobot project.
+
+the concept is not to spend hundreds of hours to implement some massive monitoring tool like nagios or something like this. instead i want to use some simple message/notification scripts which exactly tell me what i need to know.
+
+the first thing i got here is the df bot. it sends me a short jabber message when one or more disks on the serving machine are reaching a preconfigured threshold (example: 90% disk usage).
+
+
+feel free to use or improve this handy tool!

+=== Installation ===
+# tested with ubuntu 10.04
