Added a place marker to allow volume change during app. Right now it's either loud or off. There isn't a way to allow the volume to gradually go up and odwn based on the values set in settings.
-- zipFS has several limitations...
--- in a general way, seekg doesn't work... so getting a file's size needs to be done through JFileSystem.
--- getLine on files open with zipFS doesn't work so great. Not sure if it is a normal issue because files are open in binary or not... JFileSystem therefore offers a "readIntoString" function that needs to be used instead of the usual "getline" technique. However getLine can then be used on a stream connected to the string.
-- tested on Windows and PSP, I also made sure android still works, but haven't tested zip support on Android.
-- I tried to maintain backwards compatibility, but this might break on some platforms, if I broke some platforms and you can't find a way to fix them, please contact me and we'll figure something out
-- This removes wagic::ifstream. I didn't reimplement the securities that were involved in this, apologies for that. Might be useful to reimplement such securities in JFileSystem
-- I haven't tested options/profiles in a deep way, it is possible I broke that.
-- Tutorial Messages are an ability like any other, except it can only be displayed once. Subsequent calls are ignored, the ability is removed from the game as soon as it is added
-- This allows to add event triggered messages ingame. Messages are either text, or images (I don't have an image sample, but rules/classic.txt has a few examples that might help)
-- only tested on Windows, although I made sure the PSP version compiles. Hopefully I also made the necessary for it to work in the touch version (touching the screen should be enough to close the tuto message)
-- Room for improvement: possibility to choose a title in text mode, possibility to have some messages depending on others (e.g.: don't show message X until message Y has been shown), improve some of the abilities and triggers to give more flexibility, add events outside of game, to allow tuto messages in deck creator, etc...
