replaced hard-coded posts by dynamic handlebars template
load posts using ajax json request
posts buttons remove underline from text
fixed unlickable buton on mac due to transparent div above clickable ones
scroll lock no longer resizes the timeline div (to preserve scroll position)
moved spinner to prevent it from being cleared when loading content
fixed fullsize post not centered
removed unused files
not versioning blog dir (for backend cms)
can now specify the fullsize blog post url to load it from, also toggle spinner
