EPP password Escaping

[2020media]

If the EPP password contains some special characters, login to Nominet's EPP server can fail.

Error shown is
NOMINETTAG|login
{"exception":"Error 2001: Command syntax error: error at line 2: Element '{urn:ietf:params:xml:ns:epp-1.0}pw': [facet 'minLength'] The value has a length of '0'; this underruns the allowed minimum length of '6'.\nerror at line 2: Element '{urn:ietf:params:xml:ns:epp-1.0}pw': '' is not a valid value of the atomic type '{urn:ietf:params:xml:ns:epp-1.0}pwType'."}

Suggested fix - fully escape the EPP password field
