* Allows to use quickfix for references.
E.g. following mapping could be used to find references for item under
cursor and put result into quickfix list:
```
nnoremap <leader>af :ALEFindReferences -quickfix<CR>
```
Fixes#1759
* Documentation update.
Default navigation for commands that jump to new locations has been
implemented with the `ale_default_navigation` variable, and all commands
that jump to locations now support `-tab`, `-split`, or `-vsplit`
arguments for overriding the default navigation behavior.
