Regipy

* Fixed a bug when handling HvLE transaction logs
* It is now supported to provide primary and secondary transaction logs in the same command, using -p and -s respectively:
`registry-transaction-logs NTUSER.DAT -p ntuser.dat.log1 -s ntuser.dat.log2 -o recovered_NTUSER.dat `
* Fixed some serialization bugs in plugins

* Added new plugins:
* Typed Urls - Retrieve the typed URLs from IE history
* Word Wheel Query - Parse the word wheel query artifact
* Last Logon - Get the last logged on username
* UAC - Get the status of User Access Control
* Fixed misc bugs in amcache parser
* Added extraction of flags per subkey (is symlink, is volatile, etc...)
* One small plugin refactor step towards the next goal: generate a timeline for all plugin results!

* Fixed a bug while applying `HvLE` transaction logs
* Added support for old transaction logs (`DIRT` Magic)

* Fixed a bug found by hadar0x!
* Fixed a documentation typo
* Added tests for registry hive serialization
