Indentation
in the process of redoing my "source files" idea. Almost done and ready.

* when editing something in source/ subdir, bashblog regenerates the published file.
* As long as filenames are unique, it should work fine
* If you have test.html and test-12345.html published, editing the source for the latter will cause changes to the first.
* need to fix the above issue and keep testing to make sure original functionality is still there.
fixed problem when editing source file not always republishing correcct file

possible disqus fix (untested)
when backing up, backs up html, css, rss, drafts/, and source/ instead of just html files

stops blogger from trying to repost something from source

still parse_file's when posting even if didn't preview
removes any missed preview.* files

reworked some if/elif logic in write_entry
* if file exists and posting (not editing), it must be in drafts folder
* if file exists and editing, it must not be
Merge branch 'working'
