Add support for default parameter values in .reviewboardrc.
Review Request #2919 — Created Feb. 26, 2012 and submitted
Add support for default parameter values in .reviewboardrc. There are many parameters to post-review that people would like to make default, either through a repository's .reviewboardrc or through their own user's. There's also some parameters people were previously able to hard-code inside postreview.py, but that makes less sense now. These can now be set in a .reviewboardrc. The following are accepted: PUBLISH, OPEN_BROWSER, TARGET_GROUPS, TARGET_PEOPLE, GUESS_SUMMARY, GUESS_DESCRIPTION, BRANCH, SUBMIT_AS, USERNAME, PASSWORD, PARENT_BRANCH, TRACKING_BRANCH, P4_CLIENT, P4_PORT, P4_PASSWD, DEBUG, HTTP_USERNAME, and HTTP_PASSWORD.
Tested a few of these locally. The "master" branch value in this review request was populated by having BRANCH="master" in .reviewboardrc.
