remove old closed bugs and todo items to speed up wiki updates and reduce size

Remove closed bugs and todos that were least edited before 2014.

Command line used:

for f in $(grep -l '\[\[done\]\]' *.mdwn); do if [ -z $(git log --since=2014 --pretty=oneline "$f") ]; then git rm  $f; git rm -rf $(echo "$f" | sed 's/.mdwn$//'); fi; done

-`git-annex unused` has to compare large sets of data
-(all keys with content present in the repository,
-with all keys used by files in the repository), and so
-uses more memory than git-annex typically needs.
-
-It used to be a lot worse (hundreds of megabytes).
-
-Now it only needs enough memory to store a Set of all Keys that currently
-have content in the annex. On a lightly populated repository, it runs in
-quite low memory use (like 8 mb) even if the git repo has 100 thousand
-files. On a repository with lots of file contents, it will use more.
-
-Still, I would like to reduce this to a purely constant memory use,
-as running in constant memory no matter the repo size is a git-annex design
-goal.
-
-One idea is to use a bloom filter. 
-For example, construct a bloom filter of all keys used by files in
-the repository. Then for each key with content present, check if it's
-in the bloom filter. Since there can be false positives, this might
-miss finding some unused keys. The probability/size of filter
-could be tunable.
-
-> Fixed in `bloom` branch in git. --[[Joey]] 
->> [[done]]! --[[Joey]] 
-
-Another way might be to scan the git log for files that got removed
-or changed what key they pointed to. Correlate with keys with content
-currently present in the repository (possibly using a bloom filter again),
-and that would yield a shortlist of keys that are probably not used. 
-Then scan thru all files in the repo to make sure that none point to keys
-on the shortlist.
