Fix: issue #4 and #5 (#6)

- Issue #4: currently there is no official release yet so we cant
download from installer
- I added an installer debugger here to test
(f091dbf13bdf109b631951e2558651f560ca8b84)
- Issue #5: my another library
[fuzzy](https://github.com/versenilvis/fuzzy/) has a logic bug so it
causes crash, fix d479c6cb4d8453e50366c9839daaabb45a98a2df

- Other:

  - Add some tests
  - Fix reload crash (3a76e78e655fd8daafb635ec0937667325f75ee4)
