Fix for placeholder sometimes showing wrong value when not set

• Fixes a bug in the famo.us TextArea surface which causes the placeholder to sometimes have a "random" value, when not set. This was caused because the placeholder was only updated when !== '' in the famo.us deploy function.

v0.3.0

• Fixed placeholder text not being used to calculate 'ideal' height.
• Updated to new versioning strategy where major/minor version matches that of the compatible famo.us version.
