Paths with spaces don't work

When trying to use vim-dutyl in a path with spaces it gives an error saying it can't run dub describe.

A fix is to modify dutyl#util#runInDirectory to the following code. The fix uses substitute to replace all spaces in the path with an escaped space "\ ".

"lcd to the directory, run the function or command, and return to the current
"directory
function! dutyl#util#runInDirectory(directory,action,...) abort
    let l:cwd=getcwd()
    try 
        let l:directory = substitute(a:directory, "\ ", '\\ ', "g")
        execute 'lcd '.l:directory
        if type(function('tr'))==type(a:action)
            return call(a:action,a:000)
        elseif type('')==type(a:action)
            execute a:action
        endif
    finally
        let l:cwd = substitute(l:cwd, "\ ", '\\ ', "g")
        execute 'lcd '.l:cwd
    endtry
endfunction
