SBaGen release 1.4.0 (for Linux and Windows)

[Jim P. <ji...@ua...>]

SBaGen 1.4.0 is now available, with some significant additions:

- A proper installer for Windows users, setting up file associations
  and the start menu automatically, and allowing easy editing of
  sequence files.  (To edit, do a right-click then select Edit).
  Hopefully this will make things a lot simpler for Windows users.

- Randomised looping of OGG files is now implemented, with two
  standard river sound files included (recorded by me in Wales; thanks
  to John and Ann Marie for helping me out with this).

- The "p-drop" set of sequences are now built into SBaGen as the
  "-p drop" option.  Run the "prog-drop-00d.sbg" file to see how this
  works.  This means that Windows users do not need to install Perl to
  use p-drop.  Many thanks to Jonathan Bisson for implementing the
  first version of this code and sending it to me.

- A companion set of sequences called "-p slide" that change the
  carrier but keep the beat constant.  See "prog-slide-alpha-10.sbg"
  for an example.

- A feature to compensate for the low-frequency roll-off of headphones
  by boosting lower frequencies.  Useful for people who have an
  interest in very low frequency carriers.

As ever, downloads are available from my own site:

Sourceforge will follow soon.  Mac OSX users may be feeling a bit left
out right now, as there is no 1.4.0 release for them at the moment.
This is because I don't have access to a Mac right now to build the
executable.  I will get a Mac OSX release done as soon as I can.

Changes:

  Added support for randomly looping OGG files with SBAGEN_LOOPER tag
  Added two standard looping river sounds OGG files to archive
  Added <carr>/<amp> for handling plain sine tones (no beats)
  Sequence (SBG) files may now contain all options, including -i and -p
  Added -d option to select a different /dev/dsp device
  Added -c option to compensate for low-frequency rolloff of audio equipm=
ent
  Added bail-out code so that thread terminates correctly if other one di=
es
  Added -p drop builtin predefined sequence (thanks to Jonathan Bisson fo=
r
    the first version of this code)
  Added -p slide builtin predefined sequence
  Added support to look for -m files in program directory
