Rename confusing 'context' variables

no issue
- In Ghost, 'context' means the page or section of a blog we're currently within
when rendering a theme, e.g. 'post' or 'tag' or 'home'.
- In handlebars 'context' refers to the blob of JSON that is tied to a template.
- These two uses of the word 'context' have gotten very confusing, so I've removed all usage of 'context' within the Ghost handlebars helpers, EXCEPT where they actually refer to the current context (e.g. the is helper)
