Hide remote mods in mods display

[Alystrasz]

Hide remote mods in the in-game mods menu, so they cannot be enabled/disabled by players.

• Depends on Expose mods remote status to Squirrel VM NorthstarLauncher#684

Closes #798.

How to test

1. Join lobby;
2. Set allow_mod_auto_download to 1 through console (allow_mod_auto_download 1);
3. sv_cheats 1;
4. Download mod: script NSDownloadMod("nyami.mp_brick", "1.0.2");
5. Reload mods: reload_mods;
6. Go back to the main screen and check the mods list.

With this branch, the mod should not appear anymore.

Confirmed working in testing. I already had nyami.mp_brick downloaded via MAD. Before the PR it still showed up in mod list. With the PR nyami.mp_brick no longer shows up in the mod list.
