Fix Astropy intersphinx URL
Correct behaviour of inplace ufunc's for Quantities holding non-contiguous data
Introduce sidereal_time method to Time
Also changed internal use of lon, lat: swapped order in call sequence to
match convention (and coordinates), made default None, so that error can
be raised if an local sidereal time is requested, and used Longitude/Latitude
for them so that they can be defined much more easily.
Add documentation
Use explicit order arguments in format; proper spacing in CHANGES.rst
Formal sidereal_time.__doc__ such that build_sphinx is happy
Angle subclasses should decide on class; correct Latitude.__setitem__, doing
validation upfront and ensuring no temporary object is created
Add test case to ensure out-of-bounds setting of items doesn't corrupt input
Small adjustments to sidereal time documentation
Convert integers to float by default
Adjust tests to reflect that float is now default
Simplify can_cast test for numpy 1.5
Adjust __doc__; adjust comments in test for preservation of explicit dtype=int
Update examples in quantity.rst and note automatic conversion to float
Ensure that default dtype is np.float for quantity input as well
Update documentation and tests for float=default
Don't check dtype for copy=False, ensuring that that remains fast
