Homebrew Launcher 2.1

Version 1.4
support for RPX file launching from SD and wiiload/sendelf directly through HBL
new elf loader (sd_loader) code with pre-installed kernel memcpy function and support to load RPX
fixed audio clicking (thanks to aliaspider)

NOTE:
New payloads (a.k.a. MP4 files on browser exploit) are required for it to be able to load RPX files. Old payloads are still compatible but will only work with ELF files.

Version 1.3
filter homebrew launcher itself from the list of homebrews (issue 13)
fixed random freeze caused from multi threaded access to elements list in a frame (issue 6)
changed maximum depth of ELF file searching to 1 sub-directory only
fixed wrong homebrew buttons order display in some cases (issue 15)
don't allow a second wiiload/sendelf send if the first one just finished and is being started
add font smoothing thanks to @Maschell

Version 1.2 RC3
merged new gx2sploit and replaced the OSDriver exploit for firmwares 5.3.2 and higher

Version 1.2 RC2
allow MP3 and WAV background musics (file has to be located at and called "homebrew_launcher/resources/bgMusic.ogg" for now even if its not an OGG file)

Version 1.2 RC1
added official support for 4.0.0 and 4.1.0 with proper sound support
added official support for 5.5.x firmwares (only preparation still requires a kernel exploit for those firmwares)
one click link launch (no need to run the link twice or execute the exploit prior to launch (exception for 5.5.x))
removed requirement of loadiine kernel memory mapping (any mapping is accepted as long as kernel_write is available)
fixed receive from wiiload and other application that send the elf header one byte at a time
improved OS driver exploit integrated
skip ELF files starting with '.' and '_'
added version string to main view
