revamped checkmode support in user module

Browse Source 
- defaulted to commands not executing in checkmode
- added force run for info gathering (for setting changed)
- added debug for what would have been run in check mode
- added check mode for spots that made changes using system calls instead of command
- removed now redundant checkmode checks

better failure now, if i missed anything, it will misreport changed value
instead of old default of actually making the change in checkmode
