- added Makefile target to build official HBL channel
- fixed issue when launching system menu from homebrew applications
- adapted README to include proper links for portlibs
NOTE:
To build the HBL channel it is necessary to encrypt the channel with the Wii U common key for the Wii U to be able to decrypt it. Therefore a full channel release can not be distributed and everyone has to build it from sources. The key has to be saved in a file with the name "encryptKeyWith" in string/ascii format (not binary) on the root of the HBL source path. Once that is done the command "make install_channel" can be used to build the channel files (java is required for that process). To install the output "install_channel" and run the HBL channel a signature check patched firmware is necessary such as iosuhax. Big thanks to the developer of NUSPacker at this point ;).
Some homebrews will not work properly as they depend on the launcher title ID to be Mii Maker (e.g. ddd). These homebrews need to be adapted by their developers to accept the HBL title id 00050000-13374842. Additionally HBL provides much more access rights than Mii Maker does. Therefore several applications such as wupinstaller can be simplified because a launch of other titles is not necessary anymore.
