glue: resource for attaching players (and/or) vehicles to a vehicle

[sacr1ficez]

Based on MTA's community resource: glue_new

Changes comparing to original version:

• meta.xml scripts are loaded by patterns
• refactored most of code, a bit of optimizations
• few additional things to customize (see config: ShVehicleAttachConfig.lua)
• added security checks for both client and server side, a lot of them
• added player delays to prevent trigger spam
• added glue messages for few actions
• added optional ability to attach-lock vehicle using key
• added optional feature to detach all currently attached elements (for vehicle driver)
• added optional one-time hint when entering a vehicle (content is based on which features are enabled)

I think you can just name this resource "glue", because the ancient community resource called "glue" isn't official nor included with the MTA resources, and it won't be related.
