Fixed timestamps for loading and saving (CRTD and BusMaster formats), added to status bar which file is currently loaded (removed baud rates from status bar). Updated version.

mainwindow.cpp

@@ -25,8 +25,12 @@ Things currently broken or in need of attention:
 1. Need to standardize application where things might differ. All byte and bit references
 should be 0-7 not 1-8. All timings should be in microseconds.
 2. The windows that deal with canbus data should update based on incoming frames. It should not be required to load files to use these windows
+3. Test CRTD output to make sure it saves properly now
+4. Screens like flowview seem to sometimes stick with the old data after you've already cleared and loaded a different file
+5. Each screen should mention which file is loaded so that it's easier to keep track of what you're doing.
