Initial commit of SSRF mitigations.
This fixes#1908 by creating a *net.Dialer which restricts outbound connections to only allowed IP ranges. This implementation is based on the blog post at https://www.agwa.name/blog/post/preventing_server_side_request_forgery_in_golang
To keep things backwards compatible, by default we'll only block connections to 169.254.169.254, the link-local IP address commonly used in cloud environments to retrieve metadata about the running instance. For other internal addresses (e.g. localhost or RFC 1918 addresses), it's assumed that those are available to Gophish.
To support more secure environments, we introduce the `allowed_internal_hosts` configuration option where an admin can set one or more IP ranges in CIDR format. If addresses are specified here, then all internal connections will be blocked except to these hosts.
There are various bits about this approach I don't really like. For example, since various packages all need this functionality, I had to make the RestrictedDialer a global singleton rather than a dependency off of, say, the admin server. Additionally, since webhooks are implemented via a singleton, I had to introduce a new function, `SetTransport`.
Finally, I had to make an update in the gomail package to support a custom net.Dialer.
These commit includes changes to start the server as one of admin (also
IMAP) or phish server. Before this change the servers used to run in
monolith this change will decouple the two core component i.e. admin
and phish server so that they can be run independently.
This will help where admin and phish server are required to run
saperately e.g. phish server runs in a DMZ.
The available modes are `admin`, `phish` and `all`. Running the binary
in the `admin` mode will start the admin and IMAP server, while running
the binary in the `phish` mode will start the phish server. `all` mode,
which is also the default mode will start admin, IMAP and phish servers.
e.g. `go run gophish.go --mode admin`
* Added ParseLevel to set log level (#1671)
* Moved logger config into the logger package for better decoupling. Added logging tests.

This implements the first pass for a user management API allowing users with the `ModifySystem` permission to create, modify, and delete users. In addition to this, any user is able to use the API to view or modify their own account information.
* Refactoring servers to support custom workers and graceful shutdown.
* Refactoring workers to support custom mailers.
* Refactoring mailer to be an interface, with proper instances instead of a single global instance
* Cleaning up a few things. Locking maillogs for campaigns set to launch immediately to prevent a race condition.
* Cleaning up API middleware to be simpler
* Moving template parameters to separate struct
* Changed LoadConfig to return config object
* Cleaned up some error handling, removing uninitialized global error in models package
* Changed static file serving to use the unindexed package
This pull request fixed XSS vulnerabilities identified in the gophish admin panel.
**Important: These vulnerabilities could only be exploited if someone had access to the admin panel already, and could only exploit the vulnerability against the same account.**
Working on more angularjs + gophish abstraction. Gophish for backend, AngularJS for the frontend
Moved templates to partials for angular
Using FlatUI color scheme
Changed config to have "host" string
Working on simple mailing library
Some basic template bug fixes (eventually I might move the side nav to a template)
