Bug Fixes

• array out of bounds in ProfilerThread::sample(...)
• ignored input parameter ThreadPicker::AttachToProcess(...)
• cleaned up assert(...) to be able to build with Debug configuration(s)

One or more of these was resulting in bad behavior. If you select a single thread and start sampling, the app will sample a single thread once (or a few times), then begin sampling all threads.

Attach to specific thread(s)

/thread:<tid>

/thread:<tid1>,<tid2>,...

In addition to /mt /mbt, this option permits you to sample specific threads, by thread ID.

Build Scripts

• added some feedback for failures
• added support for default install paths for Inno 6
• defensively quote paths

Sorry. I'm new to git for fork/pull. I'm going to redo some things to make the pull request a bit cleaner.
