Workshop Support Additions

• Added language file en.txt to Workshop support.
• Added items.txt to Workshop support, gold/weight/sprites now editable.
• Added monster limbs.txt file to Workshop support.
• Added 'system' images to Workshop support (images/system/ files like the logo, menu backdrop, chatlog background etc)
• Closing the client with Workshop mods loaded will automatically be repopulated on next start without having to manually reselect them again. Selecting Workshop then 'Start modded game' will load up the previously selected mods.

Bugfixes

• Fixed slight delay when clicking 'start game' which could lead to some long load times due to checking if modded content was installed. Now mod content will only be checked if the 'Custom Content' or 'Workshop' menu options have been selected in the session.
• Fixed some overlapping text in the Workshop subscribed item list browser. Better handled printing out descriptions.
• Fixed Angel of Death achievement triggering off non-ally characters.
• NPCs no longer pick up invisible items (Sokoban reward).
• Fixed issue where bear traps could be placed in air gaps while levitating.
• Fixed issue where slippery fingers dropped a cursed weapon. Now item remains in hand as a proper curse should!
• Fixed Brawler achievement being disqualified if pressing the cast magic key without a spell equipped.
• Pickaxes now have a small delay when digging that prevents switching equipment during the animation. Should reduce rare bug where item durability could underflow and cause crashes.
• Fixed right-clicking on the hotbar in shop window not notifying the player where to actually click to sell items (should be in from inventory).
