#960 Now way to pylint all files

[Okko Willeboordse]

There is no way to pylint all files in a project.

There are ways to pylint some or one file(s);
1. When importing an 'Existing' project or when performing a project 'Clean' some (arbitrary) files in the project are pylinted but not all.
2. When saving a file only the saved file is pylinted.
but there is no way to pylint all files in a project.

Now we have external tooling that pylints all files such that we can check if no file has pylint issues, obviously we want this
in pydev such that when we check the 'Problems' list we know that the issues in there are all issues and when the 'Problems'
list is empty we know there are no files having pylint issues.
