fixed issue #384 and #400

For #384 Pretty sure this should work, the problem was in using slice you slice off parts of the array that may have equal or larger values and are not considered by the ng repeat. By using limitTo you consider the entire array and everything should work as intended.

For #400 Removed regex hack in app.js to transform old-style #urls into new style #/urls since this interfered with the anchor hash linking. Also removed the base href="/" in index.html since it was also interfering (causes anchor links to redirect to home page). Added anchor links to show.html under issues with post date as id and added reloadOnSearch:false in the routeProvider so each time a link is clicked the page doesn't reload. Used a css hack (pseudo element) in order to offset the scroll to the link since there's a header which covers the referenced comment. Slight problem is that pixels are hard coded so changing window size of browser affects behavior and whenever header height is changed issues.css will have to be manually changed as well. To allow bookmarking and direct use of the urls with the hash (e.g. https://www.bountysource.com/issues/447935-global-canvas-zooming-1-091#2013-09-09T12:36:48) I added a directive to run $anchorScroll after all the ng-repeats finished.
