Add regex support for run-tests command

[Alcamech]

Currently the run-testscommand supports a space separated list of test classes or empty params which runs all test. I suggest solenopsis supports a regex search feature for the run-tests command.

E.g. - solenopsis run-tests TestFile.* will match TestFile, TestFile_Foo, TestFile_Bar, TestFileFoo, TestFileBar, etc.

TestFile.*

TestFile - matches the characters TestFile literally (case sensitive)
. - matches any character (except for line terminators)
* - matches the previous token between zero and unlimited times, as many times as possible, giving back as needed (greedy)
