Replace values with variable helper (#84)

* Refactor getNodePathFromSourceRange

getNodePathFromSourceRange wouldn't go as deep as it should have,
stopping at pipe expressions, when it should have followed as deep
into the ast as possible.

The fact that it stopped early then had other part of the code base that
expected this behaviour and it effected a lot, so a rather large refactor

* overhaul of getNodePathFromSourceRange

* quick fix for moreNodePathFromSourceRange

* minor bugs in moreNodePathFromSourceRange

* couple more tests

* add moveValueIntoNewVariable

* add UI for replacing valuse with variable

* update button text
