Revert "Add platform detection"

This reverts commit 625c0dc.
Platform detection was not working. The booleans `isWeb` and `isVM` always
stayed `false`.

-### Auto Detecting Platform
+### Auto detecting
 
-The class `LogPlatform` tries to automatically identify `lineLength` and `colors`
-support for console output, depending on the detected platform (VM or Web).
+With the `io` package you can auto detect the `lineLength` and `colors` arguments. 
+Assuming you have imported the `io` package with `import 'dart:io' as io;` you 
+can auto detect `colors` with `io.stdout.supportsAnsiEscapes` and `lineLength` 
+with `io.stdout.terminalColumns`.
 
-If in VM platform it uses `dart:io` (`colors` with `io.stdout.supportsAnsiEscapes`
-and `lineLength` with `io.stdout.terminalColumns`).
-
-If you want to allow output in `stderr` (if present in the runtime platform),
-you should enable it:
-
-```dart
-  LogPlatform.enableSTDERR = true ;
-```
+You should probably do this unless there's a good reason you don't want to 
+import `io`, for example when using this library on the web.
