Add command line functionality

[DmShAl]

Hello,
Thank you for the excellent and really useful program.
I think it would be great to add command line functionality to switch presets. For example you want to add some lines to your hosts file before running one program and revert hosts file after closing that program.
Something like:

run.cmd
///////////////////////////////////////////////////
HostsFileEditor.exe -s MyHosts1
program.exe
HostsFileEditor.exe -s DefaultHosts
///////////////////////////////////////////////////

Where is MyHosts1 and DefaultHosts - your presets (archive)

I could see how that would be nice in some cases. If someone submits a pull request with some command line features like that I'd accept it.
