Test Connection does not permit host names with underscore characters.

Steps to reproduce:

1) Open the hosts file (http://en.wikipedia.org/wiki/Hosts_%28file%29#Location_in_the_file_system)

2) Add the following:

<current IP address>    mymachine_1

3) Click the Test Connection button for locations in the Test Navigator, location editor, and Windows >> Preferences >> Test preference page and note the 'Invalid host name or IP address' error dialog.

Note, the Test Connection button in the Windows >> Preferences >> Agent Controller >> Hosts preference page is successful.  

Note, the TPTP test types will execute successfully when using a host name with an underscore character.   

The symptom is caused by the org.eclipse.hyades.test.ui.internal.util.TestUIUtilities.isValidHostName(String) method that validates hostnames/IPv4/IPv6 addresses based on RFC 1123/RFC 952, does not permit underscore characters.  Although underscore characters are technically not permitted in host names, DNS names and Microsoft Windows hostnames may contain underscore characters (see http://en.wikipedia.org/wiki/Hostname#Restrictions_on_valid_host_names).
