CRAFTERCMS-128: Height change doesn't apply to RTE

Change the RTE Height to behave in the following manner:

1) RTE Height NOT set:
- Default height will be 140px

2) RTE Height set:
  2.1) Height is less than the RTE's minimum height
       - Set the RTE's height to its minimum height (i.e. 50px)
  2.2) Height is greater than the RTE's minimum height
       - Set the RTE's height to the configured height

3) RTE on Focus:
  3.1) RTE is empty or content does not exceed its set height
       - RTE's height stays the same
  3.2) RTE's content exceeds its height
       - RTE's height expands to fit all content
