Added ability to use non-printable characters in custom email body text, using \ character (similar to LOG command)

Improved Activity log and email mechanism so that new activity log is not automatically created after email is sent.

If connection takes more than 60 seconds to establish, EMUE will send an error email (if configured) and shut down.  This is especially important for Microsoft SNA server clients which cannot control timeout and may hang indefinitely.

Moved License verification from application opening to the beginning of file processing when application is opened with autostart switch, so that error an email can be generated if there is a licensing issue.

Modal dialog displayed by PAUSE command replaced with non-modal window that allows the display to be manipulated while EMUE is waiting for a response to the PAUSE command.

A change in the behavior of keyboard locked conditions has been implemented.  Specifically, if DEBUGONKEYBOARDLOCKED is set to Yes and ENABLEDEBUGGER is set to No, previously, only a message would have been logged in the activity window and log.  Now EMUE will halt execution and generate an error email.
