Added a module licenses option that lives in Legal information settings. Clicking that option opens module licenses page, which displays every module by name, filtered to exclude modules without license files. Clicking a module in the list opens HTMLViewer. Created ModuleLicensesProvider, a new ContentProvider that serves as a redirect for the Uris sent to HTMLViewer so that they open asset files. In order to provide the redirect, the provider will write the license file to a file in Settings' cache directory when the license does not exist in the cache or is outdated. The provider then opens that cached file. Fixes: 135183006 Test: robotests Change-Id: I7d69da34780c8c4efb150d0c0411078c12bc80d8
