Feature: Display Logic for Print Format Item in PDF

Goal: Functional

Description:

Now is possible to set a Display Logic for a Print Format Item rendered as PDF format.

The display logic follows the normal convention for the display logic field:

{expression} [{logic} {expression}]

expression := @{context}@{operand}{value} or @{context}@{operand}{value}

logic := {|}|{&} - these are OR and AND, resolved from left to right (no precedence)

context := any print format item column name from the report surrounded by @ - like @C_BPartner_ID@ or @Name@
        := the special values @*Page@ and @*PageCount@ are supported also
        := foreign columns can be referenced too with the notation column.foreign_column, for example @C_BP_Group_ID.Name@

value := strings or numbers

operand := eq{=}, gt{>}, le{<}, not{~^!}
