Mutex for dataPoints array to prevent crash
Almost forgot to put the mutex in the place we're actually enumerating the data while it has a potential to be written by the data recording thread.  Added that mutex.
Fixed the project browser requiring 1 second before refreshing due simply to improper dispatch queue usage.  Also commented out iPad-specific code because it was broken.  iPads behave like iPhones in the ProjectBrowser now and can actually select a project.
