[EPI] Limit Default Activity And Search Amount to 10.

Thanks to @newbie LAC for telling me where it's located. 
When you search or  look at activity The default value of items to show is 25. this changes it to 10. Might come in handy if you want to reduce resources or loading time.
Might add a custom setting to change it to whatever value you want, if I ever figure out how to implement a setting in code hooks.
