Fix cf on transactions querybuilder

[elacour]

Format fields wrongly list queue or global ticket customfields as available in transactions query builder. Results produces then empty fields.

So first, list every Transaction customfields (global and depending on TicketQueue filter if any) which will be processed as usual (CustomField.{foo} means transaction CF "foo".

Then add every ticket customfields (also global and depending on TicketQueue filter if any) as available field.They are displayed using the transaction->Object and the syntax TicketCustomFieldView.{...}.
