Modify quickfix errorformat for Gradle Error and Warning matches

- Fix match of the first Gradle error/warning in the format of
  `:proj:proj2:compile[Test]Java/path/file.java`
- Extend match to detect column location
- Remove extra line ignores (`-G`) since the last line will ignore all
  non-matching lines.
- Separate the Gradle/Javac error line match to also detect "warnings"
