Issue:Extending includepage

Description:	Includepage support for parser extension calls with parameters
Extension / Version:	DPL   /   1.8.9 on MW 1.15.1
Type / Status:	Change Request   /   open

Problem

It would be very useful if includepage could be used with parser extension calls with parameters such as the Google Maps extension. Say you have several pages describing cities where each uses the Google map extension. If this new feature was added, DPL could be uses to collect the content of all parser extensions calls and generate a google map with all cities.

Example:
City A:

<googlemap version="0.9" lat="10.00000" lon="11.0000" zoom="10">
10.00, 11.00, City A
</googlemap>

City B:

<googlemap version="0.9" lat="12.00000" lon="13.0000" zoom="10">
12.00, 13.00, City B
</googlemap>

DPL could then generate something like this:

10.00, 11.00, City A
12.00, 13.00, City B
