Prefix and RawNamingStyle annotations

Prefix is similar to @With, except it captures the entire
prefix for an argument, including an empty prefix. For example,
void foo(int x, @Prefix("forBar") bar) should transpile to foo:forBar
when using @CleanerStyle

RawNamingStyle undoes @CleanerStyle for annotated methods.
For example, @RawNamingStyle getX() should transpile to
getX, whereas CleanerStyle would transpile it to just x.
