improve crash reporting

We should look at upgrading the crash reporting we're doing from this plugin. Currently we can only get the first 500 chars of a stack trace, and can't get the exception text.

Android Studio uses this code to do crash reporting:

- android/src/com/android/tools/idea/diagnostics/crash/StudioCrashReporter.java
- android/src/com/android/tools/idea/diagnostics/error/ErrorReporter.java

Locate the plugin's current crash-reporting implementation, then compare its behavior with android/src/com/android/tools/idea/diagnostics/crash/StudioCrashReporter.java and android/src/com/android/tools/idea/diagnostics/error/ErrorReporter.java. Done means crash reports include the complete stack trace rather than only 500 characters and include the exception text.
