Run tests on AppVeyor (#385)

Fixes issue #326.

* Install target installs all executables; this is required because we don't
  actually know where MSVC builds its targets to
* Use absolute paths when running all executables
* Set `PYTHONPATH` to test directory; for some reason the Windows `sys.path`
  doesn't include the current script's directory
* In `wasmdump`, strip the directory up to the last slash or backslash
* In `wasm-interp`, Use round-to-nearest-ties-to-even when converting from
  uint64 to float or double
* Check for backslash or slash in `get_dirname` in `wasm-interp`, when looking
  for modules alongside the JSON file
* print floats in `wasm-interp` using `%f` not `%g`, since MSVC prints using 3
  digits for exponent instead of 2
* In `run-wasm-link.py`, remove file before renaming on top of it
