This pull request reverts and then re-adds some recent merges that seem to have introduced some bugs.

• Reverts "Merge pull request #50 from filestage/master" – this PR introduced breaking changes (probably bugs) to how the stubbed routes handled multiple requests to a single URL, as was reported here.
• Reverts "Merge pull request #52 from lefta/master" – this PR fixed a bug introduced in #50, but this code has been reverted.

It was hard to see the introduced bugs due to all the stylistic code changes added in the diff, so this pull request only includes the functional changes from #50.

Also added tests for fixtures generated when file size is > 70mb. This required adding the configuration option maxInlineResponseSize.

@Nanciee It's probably easier to look at this compare to see the actual code changes in this PR. This link is from just before the commits from filestage, so it doesn't include a lot of the stylistic code changes.
