[ELPA] New package: hook-helpers.el

[Ian Dunn]

    As no one has made any other objections, I'll officially submit this to GNU 
ELPA.

    It's currently maintained on Savannah, so I've included the patch for 
adding hook-helpers to the externals-list file.  I apologize if I've done this 
incorrectly.

Official Description:

Often times, I see people define a function to be used once in a hook.  If they 
don’t do this, then it will be an anonymous function.  If the anonymous 
function is modified, then the function can’t be removed.  With a function 
outside of the ‘add-hook’ call, it looks messy.

The ‘define-hook-helper’ macro is a solution to this.  Think of it as an 
anaphoric ‘add-hook’, but one that can be called many times without risking 
redundant hook functions.  It gives a cleaner look and feel to Emacs 
configuration files, and could even be used in actual libraries.
