Open local program/module doesn't work on Chrome/Safari

On Chrome and Safari browsers, the "open local program" and "open local module" options don't trigger the file input dialog. The culprit appears to be lines 74 and 132 (respectively) of mods.js which attempts to trigger the file input dialog using a generated click event. After digging around on the internet a bit, it seems likely that this is a security concern for these browsers which will only trigger a click event form an actual click from a user. I quickly tried implementing a few workarounds just to see if I could get it to work at all, but no luck. The simplest fix is probably to turn this part of the UI into an actual button that the user can click (and thus will generate a proper click event).
