1169- break out getRows

Moved getRows function from `state/stateRenderer.js` and `state/shapes.js` into `common/common.js`. Broke out section into small one line functions for replacing line breaks, then moved the `sanitize` function from `utils.js` to this new module as there is shared functionality
