[patch] Addition of "nightly-*" to ReleaseBuildProfiles

[mmadia]

From the current replies to the ​VOTE-providing-nightlies-before-R1A2-or-not thread, the return of nightly images before R1A2 is desired, as something more functional than a basic image and less featured than the alpha-* rules.

The crux of this patch is

HAIKU_IMAGE_SIZE = 350 ;
AddOptionalHaikuImagePackages Pe Nano Vision P7zip ;
AddOptionalHaikuImagePackages Development Subversion OpenSSH ;

with "haiku-nightly.*" as the suggested filenames.

P7zip compresses significantly better than zip and may be used when providing the images.

350M = raw uncompressed (about 305M is actually used)
93MB = .zip
81MB = tar.bz2
50MB = .7z
