[Android] allow unique error grouping

[ebhsgit]

Fixes

Using LogException results in all javascript Errors being grouped as one issue in the Crashlytics console.

Proposed Changes

Added new function LogError. It requires the error message, and an array of stack trace lines. Using LogError will result in grouping of Crashlytics issue based on:

• App Version
• Javascript class
• Javascript function
• Javascript line number

I purposely choose to abstract the stack trace lines, rather than adding dependency to a javascript library. The consumer of this plugin can choose how to extract javascript stack trace information.

I'm sorry - I didn't see this. I have merged it now but need to do some testing as I have made other changes.
