It should be possible to do a template call in the headerLabelPage instead of having a page per campaign per language.

So it should be possible to do:
{{Wiki Loves Monuments header|lang=$1|campaign=$2}}

or

{{WLM-is-running|$2| {{Upload_campaign_header_$2 }} |before={{Upload_campaign_header_Wiki_Loves_Monuments_2012_August/$1}}|after={{Upload_campaign_header_Wiki_Loves_Monuments_2012_finished/$1}} }}

(which would have been very useful for the contest start)

The same field can double for both purposes, it's as simple as checking if it begins and ends with {{ }}, which are illegal for a page name.

The templates should of course work as any normal template, respect <noinclude>, allow autotranslation, etc.

Note that variable $2 for the campaign name would be a new one
(we would really need {{#sub: $2 | 4}}, but that can be workarounded with an ugly switch).

Same support would be interesting for other fields like idFieldLabelPage and thanksLabelPage, too.
