Changes for DMS to Decimal Conversion

Please see the Google Maps part of the code, I've simplified the conversion from DMS to Decimal. It's 1 function versus all that stuff you had before.

I would of done the same to the Google Earth part but I kept breaking it so you might want to look at it yourself. I did however fix some of the paths in that part using os.path.join - Just so you know you can join a path like this:

```
os.path.join(addPath, 'photoEvidence')
# You don't need to add slashes, just specify each part as above and it will generate the path with all the correct slashes for you.
```
