Enhance textarea tv type

[smg6511]

What does it do?

Adds new input options to control input height.

Why is it needed?

Currently this input type is restricted to its default size of 140px.

How to test

1. Rebuild the manager template (cd to _build/templates/default and run grunt build)
2. Clear MODX caches
3. Create a few textarea type TVs to test the three new options (height, auto grow, and resize)

@smg6511 This does seem to function and it's a nice add.

One note, however, upon creation, until you change the values set for the Grow or Resizable input options, Revo throws a warning about undefined keys but once you change the input values the first time, this resolves.

It shouldn't require changing of the values as many people may not want to or need to change the values.

@jaygilmore Ok, got that covered. Thanks for taking a look.
