improve build scripts

- Add parameters to control several aspects
- Use verbose stream (4) for progress information
- Use debug stream (5) for debugging

To show the verbose stream's output, use the -Verbose parameter.
To show the debug stream's output, use the -Debug parameter.

To redirect streams (example):

./bin/Build.ps1 4>&1

Redirecting streams is useful, for example, to show output within
Sublime Text if so desired.
