added standard error of the mean to statistics_of_labelled_pixels

[thawn]

I think this should calculate the SEM, but please double check. If I read the code correctly, this automagically adds SEM also to statistics_of_background_and_labelled_pixels

@haesleinhuepf I am just working on the tests and a question came up:
should the statistics also appear in the output of push_regionprops()?
if yes, should they be inserted where they belong semantically in pos 15 below props['standard_deviation_intensity'], or where they are backwards compatible at the end (pos 36)?

furthermore, I feel confident, that I can add the code in case the input is a dict. in the case that the input is a RegionProperties object, I am less confident... (and also don't know if the standard error would appear in that case)

@haesleinhuepf I now added a simple test for the standard error. Would you like to also add the standard error to push_regionprops (see my question above?)

Yes, it seems this makes sense! Please make the backwards-compatible change as you suggested. Thank you!

@haesleinhuepf I just added the SEM to push_regionprops. Also adapted the tests accordingly.
