Dev docs: use absolute path when creating development documentation, include missing speech dict handler in NVDA 2017.4 (PR #7861) When building development docs, sourceEnv is imported again. Somehow, using `os.path.dirname(os.path.dirname(__file__))` yields an empty path, so resort to using absolute path, which then allows dev docs switch to work properly. scons/devDocs: include speechDictHandler folder from 2017.4 onwards, change http to https
