Editor doesn't left align on numbers which are left-aligned

[dsl101]

Sorry, I know this should probably be a pull request, but I just made a fix locally (not in a repo), and the patch is small, so I thought I'd post it here in case it helps.

The specific case is that I wanted numbers to be left aligned like everything else, so I changed the css like this:

td.number {
    text-align: left;
}

But the editor seems hard-coded to assume numbers are right-aligned, and so it opens in the wrong place. I fixed editablegrid_editors.js by putting a guard around the right-alignment code to check the element style is actually right aligned like this:
