Issue 398: parameter validation
Created by: meguiraun
I am quite happy now!
- routes for getting limits on motor positions (physical or pseudos) and acquisition parameters
- form validation: if any parameter in forms {datacollection, char, helical} is wrong, the problematic input field is set as warning and the "run now" and "add to queue" buttons are disabled until the user types a correct value
Notes:
- missing motor inputs limits on the client: the current implementation already prevents the user for going of limits so I have not modify anything in this regard
- long time without writing javascript so the code quality can be improved
- I am not sure if it is fully compatible with all possible hwobj
- Not tested in real world: and will not be able to test soon...
