If nothing selected use contents of file

[mneedham]

Hey,

On some of the SQL editors that I've used the default behaviour is that if you don't select the query then it will use the contents of the current view and execute that as a query.

I found myself expecting this plugin to work like that and it didn't so hence this commit :)

Let me know what you think.

Thanks for the change Mark! It definitely needed that.

Cool!

Was looking at the cypher sublime plugin which does the syntax highlighting and it solves the problem slightly differently:

    sels = self.view.sel()

    for sel in sels:
        if sel.size() == 0:
            sel = sublime.Region(0, self.view.size())

        query = self.view.substr(sel)

Maybe cleaner but more code as well!
