add 2.4.4.1 to lineup
Issue #277: split out project version parsing and add tests
minimal line-up
Issue #277: checkpoint ... working through version pattern matching using MetacelloVersionNumber>>match: and MetacelloSemanticVersionNumber>>match:
Issue #277: Semantic versioning is too stringent ... Seaside versions tend to have 4 version fields instead of three ... besides for pattern matching we are not going to compare versions so we just need a comparer that recognizes *, #, and ? characters
Issue #277: version pattern matching parsing
Issue #277: checkpoint .... added tests that revealed Issue #300 ... the two tests are wired out for the time being .... until Issue #300 is resolved ... the fix here will depend upon the techniology needed for Issue #277 anyway ...
rename MCGitBasedRepository to MCGitBasedNetworkRepository ... better name
Issue #277: checkpoint

- rename platform downloadFile:to: to downloadZipArchive:to:
- add MetacelloGemStonePlatform>>downloadJSON: (still need to implement for other platforms)
- implement tag pattern matching plus some basic tests
- still need more tests/validation
Issue #277: implemented  more tests ... because of github api rate limits, need to figure out how to specify a github username:password (rate limit goes way up) ...
Issue #277:

-add error logging for the test that could be exposed to reate limiting
- add protocol for passing in username:password for json api calls ... still need to figure out how username:password for git will be stored
Issue #302: MetacelloPlatform>>clearPackageCache since recent test failures (https://travis-ci.org/dalehenrich/metacello-work/jobs/38108725#L4203) traced to old package versions living in cache and it's possible that Issue #291 failures are due to same problem ... MetacelloPlatform>>defaultPackageCache added since Pharo wants to change MCCacheRepository api
Issue #277: siteUsername:sitePassword class inst vars will handle the first line of defense for supply credentials ... ultimately a platform specific mechanism will be called for, but it's premature to create a mechanism at this point in time...
Issue #277: add convenience method for setting site credentials
Issue #277: implement Pharo and Squeak JSON download support (blind) and re-enable the full lineup
Issue #277: focus on Pharo-2.0 and Pharo-1.4
Issue #277: error logging to see why MetacelloScriptingLoadTestCase>>testDefaultRepository is failing on Travis and not in local run
Issue #277: more logging
Issue #302: some protection for MetacelloPlatform>>clearPackageCache
Issue #302: take another tack at clearing the package cache for Squeak and Pharo
