V1.0.7 - Improve start-up/shutdown

Minor changes to improve the way the system starts up and shuts down to attempt to address Issue #3. This is not guaranteed to fix the issue though as it is difficult to reproduce the issue.

Added Polish Translation (thanks to Artur Chlebek)
Tidied up user interface text slightly.

First Release of SMSAnnunciator (V1.0.5)

First release of SMS Annunciator.
When running, the app monitors incoming SMS text messages to look for a code that indicates it is an OpenSeizureDetctor Seizure Alert Message.
If it is not, the text message is ignored.
If it is a Seizure Alert Message, a continuous beeping alarm sound is generated until the user presses the Accept Alarm pushbutton on the app screen.
See https://www.youtube.com/watch?v=tsygFTmAuuU&t=2s for a demonstration of the App in action.
