OpenNeeds IDE creates pickles in non-standard folder

[twodrops]

OpenNeeds IDE creates pickles cache in doctrees folder. The standard folder is .doctrees
This affects reusing the cache created by other sphinx-builds to support incremental behavior.

I looked into it and saw this funny sphinx behavior.

/usr/bin/python -m sphinx -b html /docs /build
generates pickles in
.doctrees

/usr/bin/python -m sphinx.cmd.build -M html /docs /build
generates pickles in
doctrees

The pickles folder is normally changed with the -d sphinx parameter only.

The second invocation style is used by needls. As a quick fix the invocation style could be changed from -M to -b.
