Finds InitializeComponent() method and renames it if necessary.
Finds all event handlers and names the args sender and e respectively.
Finds all field event handlers and names them <field>_<event>, eg.
button_Click.
This way it's possible to use a rename-all regex (.*) without renaming
symbols that shouldn't be renamed (eg. methods that are defined in an
interface in a non-deobfuscated module, eg. Dispose()). A warning is
displayed if an assembly can't be loaded.
