Опция sourceSuffixes для технологий использующих хелпер useFileList

Теперь можно использовать css-includes для сборки и обычных стилей, и ieX, например вот так:

            require("enb/techs/css-includes"),

            [ require("enb/techs/css-includes"), {
                sourceSuffixes: 'ie6.css',
                target: '?.ie6.css'
            } ],
            [ require("enb/techs/css-includes"), {
                sourceSuffixes: 'ie7.css',
                target: '?.ie7.css'
            } ],
            [ require("enb/techs/css-includes"), {
                sourceSuffixes: 'ie8.css',
                target: '?.ie8.css'
            } ],
            [ require("enb/techs/css-includes"), {
                sourceSuffixes: 'ie9.css',
                target: '?.ie9.css'
            } ]
