Allow ignoring part of history when calculating version (issue #538)

[Tungsten78]

Based on @asbjornu 's recommendations for the yaml:

ignore:
    sha: [b6c0c9fda88830ebcd563e500a5a7da5a1658e98, 6c19c7c219ecf8dbc468042baefa73a1b213e8b1]
    commits-before: 2015-10-23T12:23:15

Sequence format follows YAML and can be alternatively formatted across lines:

ignore:
    sha: 
        - b6c0c9fda88830ebcd563e500a5a7da5a1658e98
        - 6c19c7c219ecf8dbc468042baefa73a1b213e8b1

Configuration will be translated to IVersionFilters of which there are 2:

• MinDateVersionFilter
• ShaVersionFilter

BaseVersionCalculator applies the version filtering and will exclude version candidates accordingly.

Log output is as follows:

2016-04-29 13:35:02       INFO [04/29/16 13:35:02:87] Merge message 'Merge pull request #176 in PROJ from hotfix/4.03/Tasks/some-task to support/4.1.0 : 4.3.0 with commit count source 5a8c7e368552e5808b20cabad28ea022df52735f
2016-04-29 13:35:02       INFO [04/29/16 13:35:02:87] Source was ignored due to commit having been excluded by configuration

Date Filter reason is: Source was ignored due to commit date being outside of configured range

Some possible future amendments:

• Use the date filter to limit the history scrubbed by the strategies in an effort to improve overall performance.
