Allow suppression of import-module message

[3pichaxz0r]

When importing the module | out-null is ignored and messages are still written to the console. Proposed change would be to change use from write-host to something that supports out-null

[3pichaxz0r]

When the module is loaded and it attempts to change the console window title it also throws an error when run in a non-interactive environment.

The doesn't seem to be a good alternative for Write-Host at the moment :( I surrounded setting the title in try-catch block.
