src/qtweetgeocoord.cpp: 2 * bad if tests ?

1.

qtweetgeocoord.cpp:43]: (warning) Logical disjunction always evaluates to true: m_latitude > -90.0 || m_latitude < 90.0.

Source code is
    if (m_latitude > -90.0 || m_latitude < 90.0)

2.

qtweetgeocoord.cpp:53]: (warning) Logical disjunction always evaluates to true: m_longitude > -180.0 || m_longitude < 180.0.

```
if (m_longitude > -180.0 || m_longitude < 180.0)
```
