Use erlydtl 0.8.2

The `erlydtl:compile_dir` function was fixed in 0.8.2.
Fixes #419.

Also, the `report` and `return` options should now go directly into the erlydtl options, rather than into the `compiler_options` property; otherwise those options will not be treated by erlydtl, but only affect the erlang compiler, which is not what you want.
