MsiHelper should allow running an installer silently

[ShadowWolf]

The MSIHelper module statically passes the /qb flag to msiexec. It would be nicer if, instead, that was customizable in the MSIParams type (record?).

I'm new to F# but this is my likely bad re-implementation I went with since I couldn't figure out how to extend a record.

let CustomUninstall (setParams : MSIParams -> MSIParams) setup silent = 
    traceStartTask "MSI-Uninstall" setup
    let parameters = setParams MSIDefaults
    let args = sprintf "%s /l* %s /x %s" (if silent then "/qn" else "/qb") parameters.LogFile setup

    if 0 <> ExecProcess (fun info ->  
        info.FileName <- parameters.ToolPath
        info.WorkingDirectory <- parameters.WorkingDir
        info.Arguments <- args) parameters.TimeOut && parameters.ThrowIfSetupFails 
    then
        failwithf "MSI-Uninstall %s failed." args

    traceEndTask "MSI-Uninstall" setup```

I implemented this by adding a property to the parameters. Does this work for you?

Yes that works great :) Thanks!
