added elastic stress contribution to stress and shear stress vis pp

[EstherHeck]

While the elastic contribution is added to the principal stress postprocesor, it was not in the stress and shear stress postprocesors.

Before your first pull request:

• I have read the guidelines in our CONTRIBUTING.md document.

For all pull requests:

• I have followed the instructions for indenting my code.

For new features/models or changes of existing features:

• I have tested my new feature locally to ensure it is correct.
• I have created a testcase for the new feature/benchmark in the tests/ directory.
• I have added a changelog entry in the doc/modules/changes directory that will inform other users of my change.

Following PR #4002 the stress field names needed to add the elastic contribution will have to be changed in stress.cc and shear_stress.cc according to the new naming scheeme from stress_xx to ve_stress_xx etc.

Thanks updating these plugins. I think it would be good to explicitly talk about this in the documentation. Could you add a line to the documentation in at the bottom of the cc file and the header file stating that the elastic stress is accounted for if present?

Good point @MFraters, done!
I dont know why the timestepping commit is shown here now though....

That should be easy to fix with the following: checkout master, pull from the master from this repository (the default name is origin, so that would be git pull origin master), go back to this branch and do a git rebase -i master and make sure that the last commit before this one is the merge from Timo (with hash 274f11f). Let me know if this works.

Thanks @MFraters this worked!

Great :)

Can you indent the code? Then we can see the test results. You can do this by using make indent or ninja indent and commit the changes.

If it gives an error you need to make sure that you have installed the correct version of astyle (you can for example use mkdir astyle && cd astyle && wget 'https://sourceforge.net/projects/astyle/files/astyle/astyle 2.04/astyle_2.04_linux.tar.gz' && tar -zxvf astyle_2.04_linux.tar.gz && cd astyle/build/gcc && make && sudo make install).

P.S. could you change [ X] to [X] in the opening post? then it should show checkboxes with checks in them :)

[EstherHeck]

Done :)

Thanks for updating this these files and adding the documentation!

Apparently we don't have any tests which use either of these visualization postprocessors and elasticity. That might be something to add in the future.
