Merge branch 'master' into 'master'

Added support for gradle flavor specific dependencies in usual suspects check

When you have flavor specific dependencies in your project, you specify them in the build.gradle file with a prefixed *compile* command:

```
compile 'normal dependency'
myflavorCompile 'only for myflavor'
```

The usual suspects check just searches for some often used library names in the whole build.gradle file. I added another condition, so dependencies for not build flavors are not checked.
