Provide XML Methods to permanently add hot folder objects.
This can be realized with a new xml command
<modify_hot_folder folder="/samples/test">

modify_hot_folder can have one the following child elements:
<job>
<job_chain>
<lock>
<order>
<process_class>
<schedule>

All elements need to specifiy their name (or id in case of <add_order>) without path.
The Job Scheduler will then create the file regarding the naming convention for hot folder objects in the hot folder configured with the "folder" attribute.
If no folder attribute is specified, the default is "/" (root of the hot folder).
If the subfolder(s) of the hot folder doesn't exist, it will be created recursively.

If the hot folder file already exists, it will be overwritten.
