953656 - Removed all 'disable_with' references

Rails haml form builder provides an attribute called disable_with
that lets one to set a 'disabled' text on the butten when a form is
submitted. For example a button with  "Create" can be changed to
"Creating" when clicked on. However this automagical attribute doesnot
go well with ajax based calls. So this caused issues like bz 953656,
where validation failures wouldnt change "Creating" to "Create" if the
submit failed.
We are automatically disabling the button anyway without changing
the text on a form submit even without the disable_with attribute.
So removed them from all haml files. So the new behaviour will be that
"Create" button will still be "Create" but disabled instead of
"Creating...".
Bug 1017238: Adds a filter for allowing uuid specification when hitting
the System index.

This bug fix also includes changing the kt_name_analyzer back to the use
of lowercase and asciifolding since the uuid filter returns no results
given that it uses the kt_name_analyzer. The analyzer was previously
changed to support spaces in system group names through the API index
method. This case has been accounted for by adding explicit, escaped
quotes around the system group name when specified as a parameter.
