Short form for some switches for Boost Test 1.53

[Valentin Shtronda <valiko.ua@…>]

I often use --detect_memory_leaks switch which does not have short form. Attached patch adds short form for this and the rest of the switches:

-b for --break_exec_path
-x for --detect_fp_exceptions
-y for --detect_memory_leaks
-v for --save_pattern
-u for --use_alt_stack

Adds short switches where they are missing for Boost Test 1.53.

Do you know that Boost.Test supports name guessing? Thus you can use for example --save instead of --save_pattern. I'd like to keep single letter shortcuts for options which are really applicable for many users. You can also setup environment variable if you tend to use some set of runtime parameters all the time.
