introduced .tar.bz2 snapshots
- reworked write_tar_gzip_archive to handle arbitrary filter as a
write_compressed_tar_archive
- reformatted whitespaces in the said function to adhere to common cgit
standards
- added wrappers around write_compressed_tar_archive for .tar.gz and .tar.bz2
- added a hint for vim to use 8 characters shift width by default
