[PATCH] Adding command match - list matching passwords and as if print

[Michal Klempa]

Hello,
I was wondering if command searching through passwords in store and immediately
asking whether to print desired password would be useful. Tried a little and
I came with small code as a draft for discussion and proposal.

The idea is to provide 

pass match .com

which would ask for each password matching (just like in find/search), whether
to print.
Example output:
Search Terms: .com
Business/some-silly-business-site.com [y/N]:
Email/donenfeld.com [y/N]: y
sup3rh4x3rizmynam3
Email/zx2c4.com [y/N]: n

works with current dependencies (find, tree, sh). Based on grep code.
I am aware that complete fix would probably require to do some adjustments:
- clip and qrencode for matching password
- testing on other platforms
- de-duplication of code

So take this as a start for discussion, if something like this would find
its users, we can together work out, how to provide also clip/qrencode without
duplicating the code.

Best regards,
Michal
