#19 Fields not in specified order after orderFields called

[mjoseph]

Using orderFields api to control order of fields
displayed on rendered form. Fields are always displayed
in DB access order.

Tracked issue down to the following code lines:

function _dbFormParseTemplate(...)
...
foreach (array_keys($this->_fields) as $field)

should be changed to

foreach ($this->_fieldIndex as $field)

This should be changed on lines 3846, 3866, 3895,

This also corrected a problem with the removeField api
where by the field was removed but the label was still
being displayed.

Attaching patch file as well.
