phpmd on modified files

[lexbritvin]

Hello!

As I get it, linter-phpmd works only if file was saved.
Is it possible to make it work on unsaved file?

It's technically possible to do with creating a temporary file with the current contents (which would enable the possibility of lintOnFly as well). This shouldn't be too hard as the helpers module now has a method to do this for us, nobody has worked on a PR for it though.

@Arcanemagus can you elaborate on what method this is?
