Per resource / import configuration of accessibility

[nuest]

Right now global configuration variables determine for all scripts if the resources/imports/scripts can be downloaded by the user (https://github.com/nuest/WPS/commit/8693ceee5d154403eeb581be517918cbb080c335).

This functionality should be extended ...

• for scripts: Add boolean parameter to wps.des, e.g. wps.des: id = secretprocess, scriptDownload = false. A variable to set the status for all resources or imports within the script could be possible here, but seems also complicated...
• for resources: Add a parameter to the resource list for each item, e.g. in the form wps.resource: Input_Data (download = false), data.RData (download = true), other.text;. The default is the global configuration setting, which can be overridden by setting either download = true or download = false. This requires the R_Resource class to be extended to model this property.
• for imports: same as for resources
