Utilise XML escape handling on package title text values being written to the meta.xml

[Daeymon]

A common example is the "&" character, which is a valid value for the package line text boxes. But the WUP package produced will be invalid, unless the meta.xml is manually fixed to escape those characters.

Utilise the SecurityElement.Escape(String) Method method, which replaces invalid XML characters in a string with their valid XML equivalent, such as "&" with "&"
