Removed directory based entries and related

Closes #23 and closes #24. Removes everything related to multiple
pages in the viewer and now only counts words and views one entry
as one file.
Entries are now only rawtext
Removed bootstrap, use the launcher instead

On Windows, that is.
Removed unneeded stuff from viewerframe

Change page with the mousewheel (there are no pages to change) and
link-related stuff.
Removed the profile feature
Removed the blacklist feature
Removed the name filter feature

and cleaned up the related code a bit
Rawtext wrapper now stylable. Closes #13.
Added autoformatting options to viewer

Similar to kalpana-export (= I copypasted them from there) which means
you can make * * * turn into a <hr> and /word/ become <em>word</word>.
Basically a bunch of regexes to turn the raw text into pwetty html.
Added more styling options for hr + fixed style a bit
Added styling support for chapters in the viewer

Closes #25. Still could need an index of the chapters and a way to go to
different chapters though.
Added scrollbar styling for the viewer
The style autoupdates now
Added option to set window title
Changed width to max-width in the viewer css
Fixed some bad formatting in the readme
Updated the readme with config and style info
Removed the r command since it autoreloads the config anyway
Refactored the autocompletion function

Now easier to add more commands and shit there.
Added new entry command, closes #28

Now you can create entries from inside Sapfo. Rejoice!
