## Details
After migrating to engine python environment, there is no extra step required to launch resource mapping tool in editor.
1. This change is to migrate the editor tool launching process to engine python environment.
2. Add messagebox to show errors while using the tool
3. Note - as Qt binaries are not well organized in build directory, so separate out *AWSCore.ResourceMappintTool* target to group Qt binaries into independent build sub folder to solve the issue (temporarily, fix can be tracked by https://jira.agscollab.com/browse/LYN-2669, once fix is done, we can just remove this individual target)
## Testing
Runs AWSCore.Editor.Tests
```
[----------] Global test environment tear-down
[==========] 8 tests from 4 test cases ran. (161 ms total)
[ PASSED ] 8 tests.
```
1. Add support to use engine python runtime environment. Ideally we should use project executable directory which contains required qt binaries after build. But currently Qt plugins are not put under proper subdirectory which causes huge overhead of loading plugin binaries (see details in this jira https://jira.agscollab.com/browse/LYN-2669 ). The temporary solution is to use AWSCore.Editor target to create a subdirectory for our use case.
2. **Minor Fix** After migrating to engine python environment, see boto3 warning while using debug mode, seems like a existing issue for a long time https://github.com/boto/boto3/issues/454. Register a after call event to close connection
3. **Minor Fix** After migrating to engine python environment, see Qt multithread warning while using debug mode, change direct setter function call to qt signal
