Make git blame's date output format configurable, like git log
Add the following: - git config value blame.date that expects one of the git log date formats (e.g. relative,local,default,iso,...); - git blame command line option --date expects one of the git log date formats; - documentation in blame-options.txt; - git blame uses the appropriate date.c functions and enums to make sense of the date format and provide appropriate data; git blame continues to line up the output columns by padding the date column up to the max width of the chosen date format. The date format for git blame without both blame.date and --date continues to be ISO for backwards compatibility. git annotate ignores the date format specifiers and continues to uses the ISO format, as before.
