The init function of the parent class fires a progress event for 0
progress rather than a start event. UI code was assuming that progress
events should always have a start event first. This change ensures that
the start event is correctly generated.
This fixes crashes that were seen in knotty in some configurations.

When "Preparing RunQueue" shows up you can expect to wait up to 30
seconds while it works - which is a bit long to leave the user waiting
without any kind of output. Since the work being carried out during this
time is divided into stages such that it's practical to determine
internally how it's progressing, replace the message with a progress
bar.
Actually what happens during this time is two major steps rather than
just one - the runqueue preparation itself, followed by the
initialisation prior to running setscene tasks. I elected to have the
progress bar cover both as one (there doesn't appear to be much point in
doing otherwise from a user perspective). I did however describe it as
"initialising tasks".

Add a class to help report progress in a task that consists of multiple
stages, some of which may have internal progress (do_rootfs within
OpenEmbedded is one example). Each stage is weighted to try to give
a reasonable representation of progress over time.

For long-running tasks where we have some output from the task that
gives us some idea of the progress of the task (such as a percentage
complete), provide the means to scrape the output for that progress
information and show it to the user in the default knotty terminal
output in the form of a progress bar. This is implemented using a new
TaskProgress event as well as some code we can insert to do output
scanning/filtering.
Any task can fire TaskProgress events; however, if you have a shell task
whose output you wish to scan for progress information, you just need to
set the "progress" varflag on the task. This can be set to:
* "percent" to just look for a number followed by a % sign
* "percent:<regex>" to specify your own regex matching a percentage
value (must have a single group which matches the percentage number)
* "outof:<regex>" to look for the specified regex matching x out of y
items completed (must have two groups - first group needs to be x,
second y).
We can potentially extend this in future but this should be a good
start.
