Improvement to package loading instructions

[AndrewSwann]

This is just a comment on improving the suggested method of loading the code when installed via el-get or the package manager. Currently the README suggests

(let ((benchmark-init.el "/path/to/el-get/benchmark-init/benchmark-init.el"))
  (when (file-exists-p benchmark-init.el)
    (load benchmark-init.el)))

however the load function has options to not report an error if the file exists. Also by default it will start by trying to add extensions .elc and .el to the file name. I suggest you shorten the code to

(let ((benchmark-init-el "/path/to/el-get/benchmark-init/benchmark-init.el")
  (load benchmark-init-el 'no-error nil 'no-suffix))

or even to a single load statement

(load "/path/to/el-get/benchmark-init/benchmark-init.el"
  'no-error nil 'no-suffix)
