in build.sh, retry builds if it looks like xcodebuild crashed.

We've seen both Xcode 4 and Xcode 5 crash while building xctool.  To
mitigate, we're wrapping our build in some retry logic.
bumping to 0.1.11
Added a function to strip ANSI escape codes from strings generated by test harnesses in order to ensure that JSON and XML formatted output does not cause problems for parsers.

The StripAnsi() function was added to otest-shim.m and has the ability to strip all ANSI
escape codes from output strings except for keyboard change codes, which are not relevant
to this scenario.
Modified to simplify regex string.
Show currently parallel running bundle

In case tests hang, we want to figure out which test is yet running.
This can hard when tests are run in parallel.

This patch updates the info when a bundle finishes.
Note that application tests will not be reported since they never
run in parallel currently. Anyway bundle name is added for the sake
of consistency.
fix EXC_BAD_ACCESS crash when running the xctool tests on 10.9

There was a place where we never bothered to call `-[NSTask init]`, and
it started to finally bite us on 10.9.
Merge pull request #142 from cpeterso87/task-2654386
