Make tags an array in template
Strip surrounding whitespace from title
Add clean target to Makefile
Add DESTDIR to Makefile
Write new page contents to file before editing
Only show base filenames in fish completions
Update backlinks in O(n) time instead of O(n^2)

This method iterates through the entire getPages() array twice: on the
first pass it creates a table of backlinks and on the second pass it
checks each page's fname for an entry in the backlinks table.

This is much better than the quadratic time implementation that iterated
through the entire getPages() array for each entry in getPages().
Use nim's array bound operator
Only write files when backlinks have actually changed

This prevents files having their last modified timestamp constantly
updated.
Add shell completion files
Remove stale README info
Add .gitignore file
Use 'func' for procs with no side effects

This can help the compiler optimize.
Add tags subcommand
