Reset cursor on page load (Closes #206)

Stop loading themes missing smdh files - this was causing scroll crashes due to how the icon loading code was working. In the future we will include a message about how themes are skipped due to lacking smdh files. Invalid zips also caused the same issue and are also now being properly ignored

Fix memory leak in the zip file loading code

+A Theme and Splashscreen Manager for the Nintendo 3DS, written in C.\
+To-do list here: https://trello.com/b/F1YSa1VK
 
 # Dependencies
-This depends on zlib. Get it from portlibs.
+ * devkitARM, which can be installed following the instructions [here](https://devkitpro.org/wiki/Getting_Started).
+ * jansson, libvorbisidec, libpng, and libarchive, which can be retrieved from [devkitPro pacman](https://devkitpro.org/viewtopic.php?f=13&t=8702).
+ * A recent build of [makerom](https://github.com/profi200/Project_CTR) and the latest release of [bannertool](https://github.com/Steveice10/bannertool). These must be added to your PATH.
+
+# Building
+First of all, make sure devkitARM is properly installed - `$DEVKITPRO` and `$DEVKITARM` should be set to `/opt/devkitpro` and `$DEVKITPRO/devkitARM`, respectively.  
+After that, open the directory you want to clone the repo into, and execute  
+`git clone https://github.com/astronautlevel2/Anemone3DS` (or any other cloning method).  
+To install the prerequisite libraries, begin by ensuring devkitPro pacman (and the base install group, `3ds-dev`) is installed, and then install the dkP packages `3ds-jansson`, `3ds-libvorbisidec`, `3ds-libpng`, and `3ds-libarchive` using `[sudo] [dkp-]pacman -S <package-name>`.  
+
+After adding [makerom](https://github.com/profi200/Project_CTR) and [bannertool](https://github.com/Steveice10/buildtools) to your PATH, just enter your directory and run `make`. All built binaries will be in `/out/`.
