Proposed edit icon for "edit issue"

regarding https://github.com/mikelbring/tinyissue/issues/98 the usage of a common edit icon would be nice.
Merge branch 'develop' of https://github.com/mikelbring/tinyissue into develop
renamed yield to yieldContent in laravel3 framework. tinyissue should then work on newer php versions as well
Merge pull request #196 from woolfg/yieldproblem
