CF plugin leaves host name text field disabled in new server wizard

[BoykoAlex]

See the following STS JIRA for details: https://issuetracker.springsource.com/browse/STS-4024

The fix that worked for me:

if (curOldValue != curNewValue) {
   if (/NEW/ curNewValue == null /NEW/ || !!! curNewValue instanceof IServerType) {
       if (isSupportedServerType((IServerType)curNewValue)) {
                        // Disable the host name field
                        if (controlListener != null) {

Chunk of code between /NEW/ has been added to account for null values that can be selected (folders)
