Issue #1805 - Sample Points keep resetting themselves to "Pixel" 

Rename XCF property PROP_SAMPLE_POINT to PROP_OLD_SAMPLE_POINT and add
new PROP_SAMPLE_POINT.

The new property saves the sample point's pick mode plus some padding
for whatever else we might want to add. Always save the old property
too so nothing changes for older GIMP versions, and avoid loading the
old property if the new one was loaded before.
