Fixed button prompts

Commit a584cee832bd4b1b853e42c4bfc2429703b0dd15 broke button prompt and subtitle.

[illusion0001]

Subtitle is created from Draw_UserCheatsMenu() + Draw_UserCheatsMenu_Ani().

I cleaned up the code, since most stuff was already there. I can't test right now as I don't have my hardware around, but hopefully the changes still work as expected.

if you don't want the 2 Games subtitle, then a quick fix can be done:

    snprintf(subtitle, sizeof(subtitle), "%zu Games", list_count(list->list));
    if (list->icon_id == header_ico_xmb_png_index) subtitle[0] = 0;

that fixed it, any idea for the button prompt?

Should be just X Select O Back like the previous menu. it is using SetMenu(MENU_PATCHES) case in doSaveMenu.

Maybe a quick hack could be done directly when drawing the help prompt... a bit ugly, but might work. I'll commit a change so you can test if the hack works as expected.

Alright, everything is fixed then. I'll merge this PR so I can work on adding some options to this new menu to backup the current local cheats/patches to ZIP (see #11)
