allow Plugin filters to work
Merge pull request #174 from dereuromark/master

allow Plugin filters to work
Add version file.

This should help in the future if people need to know what version they
are using.
Move changelogs into a separate file after creating release notes.
Fix thrown exception

Fixes "Call to undefined function RuntimeException()"
Pass current theme as setting to filters

For cases where a filter would benefit from knowing the current theme being built (eg. the `ImportInline` filter instantiates it's own `AssetScanner` with no theme selected)
Make import inline use theme setting.

Allows importing files with theme syntax (plugin syntax already works):

    @import url('theme:css/accordion.css');
Start testing against 2.5 and pin 2.3.10
Merge pull request #177 from deizel/patch-1

Fix thrown exception
Add missing newlines to end of files and fix tests.

Add a test for #178 as well.
Merge remote-tracking branch 'deizel/patch-2'
Fix tests, I made a mistake in the previous commit.
Bump version number.
Fix missing filename in Sprockets filter's error message

Now uses two variable names so the original value isn't clobbered by AssetScanner's return value.
Make includes with theme syntax work in Sprockets filter.

Passes 'theme' setting to AssetScanner instance, so the following syntax will now work:

    //= require "theme:js/ticker.js"

Plugin syntax already works:

    //= require "plugin:Bootstrap:components/jquery/jquery.js"
Fix undefined index warning.

Forgot about cases where there is no 'theme' index in the settings array.
Adding theme/plugin inclusion tests for Sprockets filter.
Some code sniffer fixes.
