Muneeb Shaikh 47cb3e01e0 python: fixes for anaconda-mode-view-mode 
* layers/+lang/python/funcs.el (spacemacs/anaconda-view-forward-and-push):
  Added helper function to go forward and hit RET
* layers/+lang/python/packages.el (python/init-anaconda-mode):
   - use new evilification macro
   - use helper function to go ahead and push button when hitting `RET`
   - Add `C-j`, `C-k` for easy navigation in anaconda-view-mode when multiple
   references are displayed. Doesn't conflict with normal `hjkl` navigation in
   other views of `anaconda-view-mode`
