function isAbsolutePathOrUrl(pathOrUrl) {
        return brackets.platform === "win" ? PathUtils.isAbsoluteUrl(pathOrUrl) : FileSystem.isAbsolutePath(pathOrUrl);
    }
getModuleUrl returns different urls for win platform
so that's why we need a different check here
@see #getModuleUrl
@param {!string} pathOrUrl that should be checked if it's absolute
@return {!boolean} returns true if pathOrUrl is absolute url on win platform
                   or when it's absolute path on other platforms
