Update changes.txt
Changed kernel and initrd compression from gzip to XZ.
Build scripts and help documents are all updated to reflect this change.
This makes the compressed kernel+initrd image 790KiB smaller, although the memory required  for decompression increases from 0.5MiB to 5MiB. (For old hardware, you'll still need 16MiB of memory to load CPUstress either way.)
e --ultra-brute switch in upx to re-compress linpack and mprime binaries. Also compress sensors, stress, stresscpu2, and systester-cli binaries.
This saves 0.97MiB in uncompressed initrd (699KiB when compressed)
pack_buildtxz.sh: exclude initrd.xz instead.
Fix a typo in README.md
Change kernel configs so that useless components are removed.
Updated kernel config to 3.13.2.
Correct a typo.
Updated kernel config to 3.13.3
Updated BusyBox to v1.22.1
Updated BusyBox to v1.22.1
Updated Sensors to v3.3.5
Updated Intel LINPACK to v11.1.2
Update 'helpinfo' and 'menu' for the Sensors v3.3.5 upgrade.
Edit compile note glibc.txt: ld.so is better compiled with --enable-kernel=2.6.36.
Although it can work under kernel 2.6.29, it's a bad idea to let it run when libc.so needs a newer kernel (2.6.36).
