rework output options

[Gaëtan Lehmann]

output format option should take an output file as parameter, and --output should disappear. --standard-format should have "-" by default, unless --quiet is used.

report options now take the output file name as argument - closes #20

There are now 3 options to control the output format of vera: --std-report, --vc-report and --xml-report. This options take a file as argument and may be used several time. By default and unless --quiet is used, --std-report write its output to "-" (the standard or error output). The other report are not written by default. This allows for example to write the xml report in a file and the vc report to the standard output with a command like:

vera++ --vc-report=- --xml-report=/path/to/report.xml file.cpp file2.cpp

→ <<cset 5f42af521665>>
