Fixing the need for source level when running maven

When I try to run maven 

    mvn compile

I get a ton of these errors:

```
/home/mkayala/develop/mygithub/gpssync/src/main/java/net/ruthandtodd/gpssync/services/rk/RunkeeperService.java:[51,24] error: generics are not supported in -source 1.3
(use -source 5 or higher to enable generics) 
```

I'm not familiar enough with Maven to know why this is a problem for me but not you, but a quick google search found this fix.
