Deprecate GradleGenClassPathFile

[hsanson]

The GradleGenClassPathFile was created to update the .classpath used by Eclipse (JDTLS) to figure out dependencies. Unfortunatelly at some point the format seems to have changed since now the .classpath generated by vim-android seems to break somehow JDTLS that starts throwing cryptic exceptions (see log below) and the language server stops providing auto-completion, import, etc.

Is better not touch this file and leat JDTLS take care of it. Also since now we are able to dynamically modify the language server dependencies (#99) we no longer need to touch the .classpath to get Android dependencies loaded into JDTLS.
