scaleHint computation for wms 1.1.1
standard pixel converted to meters
fixing test cases for capabilities' scalehint
scale denomentator computation for wms 1.3.0
Added WMS scalehint units per pixel checkbox. When selected the scalehint is in units per pixel instead of scaledenominator.
When 'Scalehint Units per Pixel' is configured for the WMS, Compute the scale hint with a pixel size of 0.28mm x 0.28mm.
Otherwise use the min/max denominator as schalehint.
Reverted change: For wms 1.3.0 always use the scaledenominators and don't compute the units per pixel(0.28mm * 0.28mm).
wms 1.1.1 scalehint != 1.3.0 scaledenominators.
Completed the unit tests with tests for 'Scalehint in units per diagonal pixel' and as denominators.
