Reformat code - indent at 4 spaces
Fixes #8 - link to the original tiddler from the header title

The full tiddler URI is being used, it probably should be the friendly URI at some point.
Fixes #6 - links for tiddler modifier and originating space

Use a Handlebars custom helper to return the appropriate space URI based on modifier or bag URI
#5 Link SiteIcon to modifier space
Fixes #4 - Filter out the original tiddler in question

Only when the local tiddler has loaded does the search for related tiddlers happen.  This is because the search needs to know the original tiddler's bag in order to use it to filter out the original tiddler from the search result.
