Ingame mod install usability suggestions

[Ragnaman]

Quick list of things I felt missing when first using ingame mod install option:

- when user navigates to mod view (via install mods), he should be presented with search box for query text, "search" button and "show all mods" button (or some alternative to instant query for all mods without user input);
- show max 100 mods at a time, separated by pages ( 1 2 3 4 ... )...thus reducing bandwidth usage potentially;
- when mod list is loaded based on query, the list is cached/indexed/codewizardryshiz locally (changing sorting of list items should thus be instant and reducing network usage);
- give option for user to select multiple mods for install
