Pidgin Sign English -> Contact sign 

Since the prevailing term for this form of sign has justifiably shifted, as was already described in the article 
PSE is increasingly referred to as 'Contact Sign', because it doesn't display the features linguists expect of a pidgin.
 I have changed the name of the section to Contact sign, while keeping the old name as a span id for links: Manually Coded English#Pidgin_Sign_English_.28PSE.29.2C_or_.27Contact_Sign.27.
