write trans from raw.info instead of copying it from the file

ENH: making ica memorize sources to exclude

- added .exclude attribute
- sources in .exclude and sources passed on pick_sources_... are being merged
- sources in .exclude are being saved and restored
- added tests
ENH: improving test
ENH: improving doc for new feature + adding to __repr__

- update example to more clearly expose the .exclude attribute
- updating doc string to be less cryptic
- iff exclude is not empty, __repr__ will tell the number of sources marked for exclusion.

ENH: adding tests for exclude indices merging
ENH: testing dispatch of exclude to raw.info['bads'] on ica.export_sources
FIX: Importing PIL / Image
API: rename export method 'export_sources' to 'sources_as_raw'

This allows to later (0.6.) add a counterpart named 'sources_as_epochs'
which will allow us to directly create epochs in ICA space
