Improve summary line.

Summary should remove empty lines but turn eol into spaces. This makes for a
prettier summary. Though I should consider limiting the length to only 80
characters or something.
Remove todo comment.
Update readme.

README now includes some stuff about the types. This needs to updated when I've
settled on an api for this. I've also added notes about the deploy and about
actions.
No need to loop when we only index 1 file
Make summary work for rna2d.js.

The summary stopped at the first '.'. This doesn't work when things have a . in
the project name. Maybe not the best idea to have them, but there they are. This
should fix it to skip over such things and find the first sentance.
Merge branches 'master' and 'develop'
