Add option to save userid in data files

The userid of Subsurface Webservice can be included in locally saved xml
files and git repository.
For xml files, it is stored in userid tag. For git repo, it is stored
in 00-Subsurface file present in the repo.
Preference dialog and webservice dialog modified to include option
for saving userid locally.

In case of difference in default userid and userid in local file,
some semantics are followed. These can be referred to here:

Fixes #473
