Merge pull request #53 from l1ll1/master

fix a couple of bugs
Fix for CVLFAB-791. Identity menu's radio menu items were not
updated after the user's initial choice of password or key.
- Fixed issue where user could press Login button again while
    an existing Login process was already running.

- Fixed issue where event commands missing from the siteConfig
    could be silently skipped without any warning in the debug
    log.
Debug window can now be opened even before the first login
process has begun, as requested by Paul in CVLFAB-793.
Updating help to reflect Launcher's current terminology for
the choice of using an SSH key or using a password.
Removing help text which said that users would be allowed to
enter a zero-length passphrase.
Removed hyperlink to PuTTY webpage for Pageant for now, because
I can't find an easy way to ensure that the link opens in a
web browser, rather than the wxWidgets help window.
User can now submit a debug report from the Help menu or from
a new button on the debug log window.
Added a panel to the logWindow, so that the background
colour looks normal near the "Submit debug log" button.
Added "Email cvl-help@monash.edu" to Help menu.
Fixing typo.
Deleted old help file.
Using different help emails depending on display strings.
Fix for CVL-806.  Wrapping the new code to log when events
are skipped in a try/except block, because it appears to
be failing on Windows 8.
Fixed bug in new code to allow a custom help email address
to be supplied to dialogs.
Flush log before submitting.
