Use compatible APIs to adapt to the new version of Acode

According to Acode Docs, these APIs have been removed:

• editor.getSession()
• editor.getSelectedText()

And here are temporary compatibility APIs:

• editor.session
• editor.getCopyText()

Did you test this code with the latest Acode application available on Google Playstore?

@coswat I only tested for the fdroid version on Play Store because my normal version has already been updated to nightly releases.

The result is that it functions correctly, no errors found in Acode.log as well.
