Info Window - remove hardcoded default pagination

parameter for info window pagination is hardcoded for number 100.

i suggest
1. add system config: "ZK_INFOPAGING_SIZE" "defaults should be 100"
2. parameter per info window = Pagination Rows. "e.g. 25"

some issues, would be re-solved
1. hard to navigate when you have a ton of records - rows are waving
2. better customisation

tasks:
1. review how normal windows handle this issue
2. proper parameter names must be defined according to code.
2. implement above solution
