This will make sure `render :inline` is working.

Closes #1633

rails runner without any options should show usage information

Ensure engine migrations are copied in correct sequence

rafactored the regex related code in the mapper class 

Three minor fixes to tests

test_should_cache_with_trailing_slash_on_url

A trailing slash is removed when a page is cached.

What the test meant to say was : a url with trailing slash
should be cached and the cached page should not have any
trailing slash.

This patch clarifies the name a bit.

Make sure `escape_javascript` return `SafeBuffer` if the incoming argumen

remove unused UserController from test

Fix engine's generator

Fix "warning: assigned but unused variable" on AR tests

class WithSymbolReturningString is not used anywhere in the test.

Date#freeze fails when called more than once in 1.8

Instance variable not used.

Simplify boolean logic into ternary

Secondly it seemed from the method that the intent was to test a case
where layout was declared in a symbol and the method named mention in
layout returns nil.

That case is already covered with class     class WithSymbolReturningNil .

Also the case of SymbolReturningString is covered with the class
WithSymbol.

If you set a js_compressor, it means that you want shit compressed -- we dont need a second option to turn that on

Update CHANGELOG to mention the new SafeBuffer change
