Update bootstrap-datetimepicker.js

Added formatViewType option for a time only picker. Setting it to "time" and using correct view restrictions will allow for a time in the datetimepicker header instead of a date (which is invalid for a time only picker).
Update bootstrap-datetimepicker.js
adding support for pickerPosition: top-left and top-right
initialDate should be more important

For example: if element is input then initialDate is ignored. This is a quick fix.
