Added some truncation to the swt notifications

Notifications on the SWT environmental integration now
get truncated to 100 characters.

Because SWT tooltips don't handle long mesage bodies very
well I've made sure that it gets truncated to 100 characters
it is not ideal but is a solution for now. This is a small
improvement to issue #7.
Merge branch 'develop' of github.com:MMS-Projects/copyit-app into develop
