Not all arguments are supported for Paket commands

Found these as part of https://github.com/cake-contrib/Cake.Paket/pull/29, Cake.Paket doesn't support any of the following arguments currently

I won't suggest supporting `--help` on any commands, as there's no use in cake?

### All Commands

- [ ] `--silent, -s`
- [ ] `--verbose, -v`
- [ ] `--log-file `

Silent and verbose could be hooked up to the log level in cake? Not too sure if log file is useful for anything?

### Paket Pack
- [x] `--interproject-references `
- [x] These can be used multiple times, however settings only allows one value
- [x] `--exclude `
- [x] `--specific-version `

### Paket Restore
- [ ] `--target-framework `
- [ ] `--output-path `

I'm happy to add any of these btw :)

Exclude and specific version could be updated to accept collections of values? The other are straight forward enough.

Start by reading the Cake.Paket command implementations and settings for Paket Pack and Restore, then trace how command arguments are mapped. Review the unchecked arguments in the issue, including repeated --exclude and --specific-version values. Done means the agreed arguments are supported and their behavior is covered by the existing project checks; clarify the log-file and collection decisions first.
