Rearranged sequencing of audio streams and devices.
The code was starting streams linked to closed devices which may be causing issues on the Mac version. I have refactored to ensure that devices are always opened before related audio streams are started. Made .h C++ headers emacs friendly. Removed some code in the MainWindow contructor that read the log file but failed to check if the file exists and didn't do anything with the data anyway. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@3977 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
