[Bug Fix] Zone Heading for Binds, Summons, Teleports, and Zoning. (#1328)

* For as long as I can remember people have had issues with zoning in, facing the wrong way, and walking through a zone line.

With this we will be able to set zone's safe heading as well as preserve heading on summon (NPC or GM) and teleports between zones.

This affects several pre-existing quest methods and extends their parameters to allow for the addition of heading.

The following functions have had heading added.
Lua
- client:SetBindPoint()
- client:SetStartZone()

Perl
- $client->SetBindPoint()
- $client->SetStartZone()
- quest::rebind()

SetStartZone parameter list was fixed also.

This converts some pre-existing methods from glm::vec3() to glm::vec4() and has an overload where necessary to use a glm::vec3() method versus glm::vec4() method.

This shouldn't affect any pre-existing servers and will allow PEQ and others to document safe headings for zones properly.

* Removed possible memory leaks.

* Fix SQL.

* Fix client message.

* Fix debug log.

* Fix log message.

* Fix call in rebind overload.

* Fix floats.

* Add default to column.
