* [v2] Add support for post build hooks
Currently only supports build-level hooks
* [v2] Improve build assets handling and use single source for manifest generation

Breaking Change: Windows manifest file must be named
“wails.exe.manifest” and doesn’t depend on the project name
anymore.
* [v2, windows] NSIS installer generation
