playerblips: various improvements

[jlillis]

When merged, this PR will make various improvements to the playerblips resource:

• Refactored settings config so they appear in admin and admin2. This breaks backwards compatibility as the setting names had to be changed. The major version of the resource was bumped accordingly.
• Added *blip_range setting to adjust the range at which blips are shown on the minimap
• Added optional playercolors integration and a new setting: *use_nametag_colors
• Modified freeroam to use this resource for player blip functionality, rather than it's own code.
• Fixed a debug error that occurs when other resources (i.e race) destroy all blips attached to players
• CRLF -> LF: this makes the final diff look weird: just follow along from 5853a42

I'm happy with this and would like to merge, but would appreciate a second set of eyes per repo policy.
