Added splitdate()
 </summary>
 <description>
Fulfilling enhancement request #1589, I have added a splitdate() function.
Example:
- dq.splitdate('today')
[mjd=51778.948, year=2000, yearday=235, month=8, monthday=22, week=34, weekday=2, hour=22, min=45, sec=5]

Correct stack and added functionality
 </summary>
 <description>
Corrected the stack behaviour of the quantagui RPN calculator. In addition I added functionality:
- I added an indicator to show if the field is being entered, or is a
correct top of the stack, or is incorrect and should be edited
- I made the entry window the top of the stack (I think this was the
easiest way to really copy normal rpn calculator behaviour)
- I added a button to enable (re-)editing of the top of the stack (maybe
after some external data is pasted in)
- I added a deg/rad choice. 
- if no units given for a sin(x) I will assume the selected units
- for inverse functions (asin etc) the result will be in units chosen
- log and exp added (only for undimensioned data), and sqrt (only if
units dimensions are even)
- added dms and hms formatting for angle like data (or time, or with
selected units)
