Lock regexp.prototype.flags version

[MisanthropicBit]

Version 1.5.1 of regexp.prototype.flags switched out a package that has missing dependencies so once node-dba is bumped or freshly installed (by someone who recently got a new laptop) then the dba tool fails with a require stack for a missing package.

The plan is to temporarily lock the version to at most 1.5.0, bump test, bump data, and then bump node-dba although the issue is likely to be resolved quickly but the author is perhaps asleep.

If you encounter this issue you can either do npm -g install -D functions-have-names or run npm -g . in your local node-dba repository as long as your version of regexp.prototype.flags isn't already v1.5.1 (npm explain regexp.prototype.flags).
