alignValue.toFixed is not a function (suggested fix included)

[nyndesigns]

I was testing out an implementation of the time picker with some new code -- when my firebug blew up with error messages (alignValue.toFixed is not a function) while sliding the minute field.

The site is using jQuery ui 1.8.17 and jQuery 1.6.4 -- running Firefox 12 on Ubuntu 12.04.

Anyways, after a quick search I came upon this thread (http://forum.jquery.com/topic/alignvalue-tofixed-is-not-a-function) in the jQuery forums. As suggested, I wrapped each value (value, min, max, step) within the slider function (line numbers: 469, 484, 496, 508, 768, 770, 772, 774) with parseFloat().. This seems to have corrected this issue.

I'm pretty busy atm.. so I haven't had a chance to look at an optimization (primarily, to see where adding parseFloat is necessary and where it is not), to test other versions / combinations of jQuery, jQuery UI, etc.... and to obviously push these suggested changes.. in the meantime, if someone else has a chance to look at this, can confirm it.. or just stumbles upon it from a web search.... great :)
