Fixed Lua errors:
- lua/weapons/gmod_tool/stools/streamradio_gui_color_individual.lua:72: attempt to index field 'Tool' (a nil value)
- lua/streamradio_core/client/cl_vgui.lua:137: attempt to call method 'SetPlaceholderText' (a nil value)

These errors happend on outdated GMod versions or on joining servers with an older addon version.
The tools will not load instead of throwing errors.

See this: [Update] Major update January 2018

- Fixed error: addons/3d stream radio/lua/entities/base_streamradio.lua:369: attempt to call field 'Restored' (a nil value)

- Added more helpful information for error 410, 420 and 421.

- Fixed covered radio volume always being active which made the radio quieter than necessary.

- Fixed a Lua error.
- Add error help for error 4 and 37.
- Removed and disabled SoundCloud stuff, as the radio can no longer support this because of legal reasons.

- Volume changes: This only works if the latest version of gm_bass3[facepunch.com] is installed on the client!
* Made the 3D Sound louder.
* The global volume can be set up to 10 now.

- Improved animation on the radio models.
- Fixed radio breaking sometimes on toolgun use.

- Removed shipped SoundCloud examples.
- Added RadioRecord.ru playlist.
- Added ConVar: sv_streamradio_rebuildplaylists_community_auto 0/1/2 (Default: 1)
* Set how the community playlists are rebuild on game start.
* 0 = Off,
* 1 = Rebuild only,
* 2 = Delete and rebuild
- If sv_streamradio_rebuildplaylists_community_auto is active then you can no longer save or change playlist files in the community folder. This is to prevent confusion and data loss on game start.
