Added arguments for functions for display in the environment viewer
even up empty panel sizes

by fixing the padding of dataframe viewer
fixes #1079
copy full_name attribute when duplicating notebook tree entries

fixes #1053
closes #1097

@agrawal-mohit, thanks, your investigation pointed out the root cause of the bug
i think it's better to make sure the attribute is populated rather than using
another attribute, however.  because sometimes the short name is not descriptive
and we need the full path (from full_name)

Merge branch 'pr/1043' into develop
blindly copy all ace r mode stuff from ace-cpp-autoindent

and replace defined/require mode/ with ace/mode/
adapt ace.js (ace/editor.js) for ace-cpp-autoindent getNextLineIndent

indentation seems to work
Merge branch 'feature/auto-indent' into develop
Merge branch 'develop' into feature-compute-separation
