proxy property fixes

promote ExpressionOnHide to code_proxy panel class

if luapad is active, mirror changes from normal property text field to the luapad screen (the link is now bidirectional)

convert vectors when pasting so they work out of the box with commas and no unnecessary trailing zeros, this is also to prevent an error where it tried to string trim a vector
