Add accessors on process to get & set the selected thread by IndexID (useful since that's the one that "thread list" shows and it won't get reused even if the underlying system thread ID gets reused.

SBThreads can be referred to by their ID, which maps to the system specific thread

identifier, or by IndexID. The ID may or may not be unique depending on whether the

system reuses its thread identifiers. The IndexID is a monotonically increasing identifier

away it will not be reused.
