**Notes**

This update allows custom plugins to override the builtin rez plugins. It does so by reversing the order
in which plugins are loaded, so that builtins are loaded last.

**Notes**

This release fixes an issue on Windows, which has non-case-sensitive filepaths. Requesting a package with a case
differing from that on disk would cause two packages to exist in the resolve, which really were just different
cases of the same package.

The behaviour on Windows is now:

- Packages are case-sensitive - `rez-env Foo` will fail if the package folder on disk is `foo`;
- Package repository paths are case-insensitive - `~/packages` and `~/Packages` are regarded as the same repo.

**Merged pull requests:**

- [FIX] Make package resolve request respect case sensitivity -- Windows [\689](https://github.com/nerdvegas/rez/pull/689) ([lambdaclan](https://github.com/lambdaclan))
