Update DataMapper sake tasks

gistfile1.txt

NOTE: run all the commands prefixed with "$" from the command-line.

0) Make sure sake is installed:

  $ sudo gem install sake

1) Make sure you've applied this patch to sake:

     http://err.lighthouseapp.com/attachments/50325/sake_rake_0.8.2.patch

  This fixes a bug that would cause the error "can't convert true into String" to
  be shown everytime you attempt to use a sake command.

  (I do not know why there has not been a sake release with this fix baked in)

2) Run the following command to clean out any old dm related tasks:

     $ sake -T | egrep '^sake (dm:|strip\b)' | cut -d" " -f2 | xargs sake -u

   This should only need to be done one time.  The reason for this is that
   the tasks reference URLs on datamapper.org which no longer work.  Since
   I don't (yet) control datamapper.org I can't really fix this problem.
   Sam and I are in the process of transfering the domain.

3) Install the latest DM sake tasks:

     $ sake -i http://github.com/dkubb/dm-dev/raw/master/dm-dev.sake

4) Use the following command to download the git repo, and install the
   latest DataMapper source from the "master" branches:

     $ sake dm:gems:refresh

   NOTE: this will uninstall all existing DataMapper, DO and Extlib
   gems on you system.
