* Refactored keydata handling.
* Sealed NCA KAEKs are now generated at startup, and NCA key area entries are now decrypted by keysDecryptNcaKeyAreaEntry(), reducing the number of calls to spl functions.
* The eTicket RSA device key is now retrieved and decrypted at startup. RSA-OAEP wrapped titlekeys are now decrypted by keysDecryptRsaOaepWrappedTitleKey().
* Renamed titlekek -> ticket common key throughout the codebase.
* Added NcaKeyAreaEncryptionKeyIndex_Count and NcaKeyGeneration_Max enum values to nca.h.
* Proper usage of strcasecmp() in some functions.
* Moved syscall hint checks from keys.c to mem.c.
* Define illegal FS characters as an array rather than a char pointer.
* Services are now initialized before the CFW type checks.
* Fixed pcv/clkrst service initialization.
* Implemented additional thread safety and logfile output to service functions.
* Slightly tweaked running service checks.
* Added proper Markdown documentation for the USB ABI.
* Added text files with required module information, which can be used with pip.
* Added a batch file to build a ZIP archive with a standalone copy of the script, which can be used to run it under Windows systems without Python.
* Further tweaked the way the progress bar window works.
* Debug messages are no longer printed to the log.
* Rearranged some parts of the code.
