sorts .gitignore and adds *.sublime-* to ignore Sublime Text project files.
Adds .bowerrc to allow users to more easily customize output directory for bower packages, and adds corresponding lodash templates in the Gruntfile to automatically read and use whatever directory is specified.
removes unnecessary `layout` property from YAML front-matter of pages, since it's already defined in the Gruntfile. Also removes `marked` options that match defaults already defined in the helper.
updates page titles to be consistent in YAML front matter. Adds templates to layout to automatically generate page titles and ids and removed the `# h1` from each page. There is no material difference in the compiled HTML - except it's more consistent, and no visual difference in the browser.

Also makes use of {{slugify}} helper to generate the ids for h1 tags, and the {{default}} helper to DRY up the conditional logic around meta titles and descriptions.
replaces arrows with &raquo; in footer to ensure that they render properly and won't be escaped by marked.js.
adds `{{rel}}` helper to make relative paths a little easier to maintain.

In package.json, the names of handlebars helper modules were also added to the keyworks array,  this is a convenience of Assemble to get around having to define the helpers in the Gruntfile. If this is too abstracted we can put the helpers directly in the templates/helpers dir and register them in the Gruntfile.
