Changes pertain to app creation page, specifically app name with namespace input fields

- Remove font-family because (a)it's causing a weird height descrepency issue on FF and (b)it's superfluous
- Change explicit height to min-height. It was part of several issues that were causing the input and .add-on's to have different heights at different widths.
- Adjust width between label and controls at <979px width, because of horizontal scroll.
- Apply min-height at <767px so .control-group-important elements have consistent heights.
- input-block-level mixin needs slightly taller min-height to account for descrepency on FF at mobile res.
- Reapply span3 (same as prod) to control both input widths at specific browser widths.

On errors, the p.help-inline message was missaligned and a different size than the rest of the help text.

Remove span3 class width from select.

Needed because FF on Mac sets line-height based on font-family, ignoring form field explicit line-height
causing inputs next to span.input-append and/or span.input-prepend to have different heights when set to Open Sans.Assigning "Lucida Grande", "Lucida Sans Unicode", "Liberation Sans" because they most closely resemble "Open Sans" for each platform.
Bug 1021472: Correctly migrate cart dependency dirs
Don't use app_dns == gear_dns with update_cluster

Previously update_cluster was only syncing content to and activating
new gears if the proxy gear in question was the original one
(OPENSHIFT_APP_DNS == OPENSHIFT_GEAR_DNS). Instead of doing this,
modify the broker to select a proxy and pass a boolean indicating that
proxy should do the syncing and activating.
