Go Regexp repetition limit.

[ArmanHZ]

Following hash regexp rules exceed the 1000 repetition limit set by Golang:

• {"GRUB 2", 7200, "", false}
• {"Microsoft MSTSC(RDP-File)", -1, "", false}
• {"1Password(Agile Keychain)", 6600, "", false}
• {"Android FDE ≤ 4.3", 8800, "fde", false}

Another detection mechanism is needed for these.

as discussed in an off-site discussion it'd make sense to have a closure callback instead of the raw regex. this would allow for more complicated rules, and allow us to handspin the detection for the regexps that exceed the 1000 repetition limit :D

GRUB 2 hashes are now supported; see ce4a916
