pylint cleanups
support additional-options in bootstrap()
fix broken python 2.6 tarfile support
add sandbox.sh install-service command

- this does a best effort service install in the current environment
  only supports chkconfig or update-rc.d
fix several bugs introduced with tarball datasources

- always check for required system files and don't apply filters
  (ib_logfile* ibdata* aria_log* etc.); This is not exhaustive
  and will likely need other entries added for less common
  configurations in the future
- always convert a file path to a (decoded) tablename.  This
  uses mysql.frm.tablename to decode the mysql filename encoding
- log excluded items
move logic to detect existing ib_logfile0 to generate_defaults

- generate_defaults now detects a non-standard ib_logfile0 exists
  and automatically adjusts the my.sandbox.cnf to the installed
  value
add innodb-log-files-in-group option to my.sandbox.cnf template
update sandbox.sh template

- add missing version="<installed sandbox mysqld version>" variable
- ensure install-service actions are echo'd consistently
update dbsake urls to point to docs.dbsake.net
change DBSake -> dbsake
update subcommands documentation

- add a global dbsake usage section at top
- add "Usage", "Examples" and "Options" section to each subcommand
removing very stale contrib/dbsake.man.rst
add dbsake.1.man - sphinx generated manpage from current docs

- This is pregenerated as sphinx 1.0+ is not readily available
  everywhere.  On platforms where it is, this file can be
  created from source by running 'make man' in the docs directory
