Lots of interconnected changes in this commit:
- Removed unnecessary name/author/filename members all over the place.
- Started using exceptions to deliver preset loading and rendering errors to the topmost ProjectM class.
- Added stream loading methods to factories and the base Preset class.
- Added new events for requesting preset switch and telling the user about loading errors.
- Consolidated preset switching logic in ProjectM class a bit.
The native presets did not build anymore due to refactorings, cause other build issues on Windows (e.g. require linking to psapi.lib) and would need a complete makeover anyway.
Scanning textures/presets dirs for textures and scanning preset dir for presets.
Scanning is now done recursively, so presets and textures can be organized into subdirectories instead of needing to be flattened into a single directory.
On POSIX systems makes use of [ftw](https://linux.die.net/man/3/ftw) which should be relatively efficient. Otherwise falls back to recursing with `dirent` (for windows).
Probably should have made an autoconf check for `ftw` instead of doing `#ifdef WIN32`.
* Scan subdirectories in presets directory
* remove preset subdir config
* Recursively scan for textures too, add c++-17 compatibility
* Refactor directory scanning code so it's reused by texture loader and preset loader. Make cross-platform (maybe)
* filescanner in makefile
* extension filter for file loader
* make extensions match up'
* need string.h
* Add FileScanner.cpp to win build (maybe)
* scan all dirs
* #ifndef #ifdef is def fun
* bogus comment
* bleh
* bleh
* itunes plugin with c++17
* EyeTunes needs to know about the FileScanner
