Subject: Be more careful about the files that we move to C 'src' directory:
 since there is no header files starting with "org_" except JNI files, moving
 the "org_*.h" file should guarantee that we will not overwrite non-JNI file.
 The use of wildcard is for "org_osgeo_..." which may be added in a future
 version.

This commit also opportunistically fixes minimum Ant version number
in documentation.

Subject: Revert "Set projection plot scale to 100% for better PDF output"

This had unexpected side-effects when building the HTML docs on Travis
compared to locally. The correct solution would be to set different
scaling depending on the output.
