Just wondering, is it beneficial to move some of these default form values into a separate file/helper so we can set the defaults in just 1 file?

• Used redux-form instead of formsy. So far, it has been easy to work with. I've adapted the wrapper macros from redux-form-material-ui. Not using the redux-form-material-ui directly since we want more control, e.g. can default all TextFields to have floatingLabelFixed. Quite a bit in this PR already - we can add wrappers for the other components in a next PR.
• One issue with redux-form is that the intl object is not (easily) available in the validation function. Instead of setting error strings directly, set the translation object.
• Spent some time to create a date-time input where dates can be copied in. It is slightly makeshift since I'm using only whatever Material-UI exposes, but good enough I think. Once merged, will use this for lesson plan edit as well.

If this is required, means we cannot use it without redux-form ?

Separated the wrapper and underlying component in the latest push

Maybe making intl a global key value store will help ? but we can use this way for now.

LGTM !

Yeah, it's starting to look like a good idea. Quite troublesome to keep doing injectIntl and the date/time formatting feature can be better done with moment.js. (Although I wonder if we should keep date/time unlocalised as 31-12-2017 and 23:59 for some places like in v1.)

@kxmbrian think this can be merged after the build error is fixed.

Thanks for the date time input, should be really useful !
