Added: debug info window (console command "show_debug_log()") that is rendered on screen for live feedback during debuggin.
Changed: to custom debug_log_enabled variable and add_to_log function.

Fixed: allow for expiration 0 where there is no time based clearing of cache and only old items get pushed out when max_size is reached.

Missing from previous commit, changes in preference screen (remove option for memory settings, changed layout a little, reduced text size).

Removed: choice options for memory mode (pc =1, mobile = 0), remove option for user to change it, always clear on day change (girls will be wearing new outfits anyway).

Optimization: run_move now only handles the move, the outfit is determined by the wrapper of the called move_person function (in effect we were setting the outfit twice).
Fixed: clothing fading during stripping requires a flattened overlay that is faded out, also make sure we draw them at the correct zorder.

Fixed: set correct schedule for Sarah's friend and renamed her to Naomi (also don't delete global ref and add her to the unique character list). She's now ready to use in another part of a story-line, only need to change her schedule when she reappears.

Fixed: removed calls to old cheat module and fixed hair_style / hair_colour changes to update correct properties on editing target.
Optimization: check editing target attribute availability before loop.

Fixed: condom dialog now differentiates between anal and vaginal sex so no more getting pregnant dialog when having anal, also condomless sex taboo (pregnancy related) is not broken while doing anal.

Added: background image replacements now create a range of default bedrooms with their own backgrounds.

Increased: cache size to 500 images per position
Optimization: only lock when accessing zipfile and placing data in cache or reopen zipfile

Added optimized build_person_displayable()
Removed: Flatten() function calls, according to renpy documentation should be avoided if possible.
Removed: animation support all together (incl. pref setting)

Experimental: added LRU cache to reduce file loading from ZIP files and increase responsiveness of UI.

Fixed: others variable no longer exists here -> use people count for location to determine if other girls are around.
