* Fixed potentially unhandled exceptions when app is loading
  its config file.
* WIP: Introduced user configurable list of macros which are
  auto assigned to keyboard accelerators (F1 ... F12) and
  saved along with the app's config file (added under new
  main menu bar section "Macro").
* Bumped version (1.0.0.svn38).
