New Features, Better Networking, Faster Performance

- Added option for cursor in VR.
- Added button for switching playback mode (no loop, song loop, playlist loop).
- Added option for the playback mode to the Toolgun.
- Added/Changed Wiremod ports represent the playback mode.
- Added support (including the GUI) for the Wiremod User entity. It can be used in contraptions to trigger use operations (+use) as like as a player would do on other entities.
- Changed playlist icons to a new custom one.

- Moved networking from NW2Vars to NWVars, because NW2 is actually a buggy unfinished mess.
- Fixed multiple cases of networking being unreliable casing the radio being wonky in multiplayer. It should be much more robust now.
- Reduced networking overhead, by utilizing string tables for repeated strings.

- Improved overall performance. Fixed potential memory leaks.
- Fixed huge FPS drops when seeking songs. This happened also when the radio synchronizes between players or other radios (master / slave setup).
- The GUI is no longer re-rendered every frame when radio playback is paused or stopped. It still has too when it play backs a song, though.

- Fixed several UI / UX bugs, causing hiccups, stucked playback and other wonky behaviors.
- Replaced hacky hashing algorithms (for networking). Because the game actually ships with decent official ones now, we no longer have to abuse util.CRC()

- Remove the use of CompileFile() for loading, as it was not needed at all and it could trigger some anti-cheat addons.

- Code cleanup, respecting native Lua syntax more

Reupload after upload error.

- Fixed Lua-Error: lua/streamradio_core/client/cl_vgui.lua:22: attempt to index field 'Stream' (a nil value)

Fixed custom URL blocking ("sv_streamradio_allow_customurls 0") not working properly, added more requested playlists.

- Might fix some Error 20 cases.
- Added Playlists: GalNET.ru, Nightwave Plaza, NonStopPlay

Playlist, model and tool panel update.

- Added support for 3 radio models from 2 addons.
- Fixed broken community playlists. Added "WCCK dead" and "Deutsche Welle" playlists. Removed Radiorecords.ru playlist, because this station is no longer compatible with this addon.
- Added a button to the tool and settings panels to switch between those more easily.
- Updated model selector note on the tool panel.

Run sv_streamradio_resetplaylists_community on the server to apply all playlist changes after the update.

- Fixed an error in playlist editor during folder delete.
- Fixed an error on loading addon toolgun menus.

- Improved Dropbox support
- The radio auto-converts input Drobbox URLs to their internal download URL on input.
- Added limited support for media that can not be played back in "noblock" mode. This media can not be played in sync and it can not be seeked in.

- Improved caching
- Fixed it being broken
- Increased max sizes of cache files to 256 MB (64 MB before) per file or 16 GB (1 GB before) total.
- Increased max count of cache files to 1024 (128 before)
