Title: Fixed issue #1382

- Ashtech driver is no longer checking fix status from comparing
coordinates to 0.0;0.0;0.0, instead it's checking fix type in GGA or
checking coordinate exsistance in POS. This removes compiler warning
about float euqality comparison.

- Fixed compiler warning about comparison between signed and unsigned
int

- Fixed compiler warning about class property masking
