Print run() commands in worker console

* Add line by line comments for run()

Remove is_not_ready.html and use log.html instead

* is_not_read.html deleted

* views.py: replace render_template('project/is_not_ready.html') with
redirect(url_for('project.log'), except in log() where it is removed to
stop a loop error, so accessing any other pages until
project_git_sync() completes will show the log page

* tasks.py: create config at end of project_git_sync() so that ufo and
txt files are populated in setup form

* log.html title changed

* macros.html Log tab added to nav()

* utils.py Added fd.flush() to RedisFd().write() so that process.log is
written as its happens, and therefore log page renders log as things
happen
Fix: Actually add self.fd.flush() (see previous commit log note)
Fix: Add close_fds=True to Popen() calls, to prevent 'IOError: [Errno 24] Too many open files'
Minor: log tweaks
Fix: Copy license file if it exists in a subdirectory of the _in repo
Fix: Actually create config after initial git sync
Improve 'scroll to top' link on log page
