### Minor Analysis Improvements

* Added models for the libraries OkHttp and Retrofit.
* Add taint models for the following `File` methods:
   * `File::getAbsoluteFile`
   * `File::getCanonicalFile`
   * `File::getAbsolutePath`
   * `File::getCanonicalPath`
* Added a flow step for `toString` calls on tainted `android.text.Editable` objects. 
* Added a data flow step for tainted Android intents that are sent to other activities and accessed there via `getIntent()`.
* Added modeling of MyBatis (`org.apache.ibatis`) Providers, resulting in additional sinks for the queries `java/ognl-injection`, `java/sql-injection`, `java/sql-injection-local` and `java/concatenated-sql-query`.
