Make pointcloud and pointcloud_postgis versions match

Previously the version of pointcloud was 1.1.0 while the version of
pointcloud_postgis was 1.0.0. With this commit we ensure that the
versions are the same.

This commit also adds a PC_PostGIS_Version function that returns
the version of the pointcloud_postgis extension.
