Version 2.5.2

• Added new srctools_paths.vdf config, allowing specifying the base location for all paths in the main config.
  This separation allows mod projects to synchronise the main config, while customising the new path config for installation locations on each computer.
• Fix scriptlist being used in pre-L4D2 branches.
• Fix an issue causing a single brush face in the map to be "missing" a triangle.
• Add some support for Portal 2 Educational Version and The Stanley Parable (via @Adrthegamedev).
• Clarify that Portal 2 uses maps/map_name_particles.txt.
• Ensure culled bases are replaced by their own bases (fixes Item, for example).
• Update to Mapbase 7.1, and add Entropy Zero 2 entities.
• Added icon for npc_heli_avoidsphere.
• Change propcombine/geocable to log just the number of culled models, not every single file.
• TF2 now has VScript support, updated FGDs to include the corresponding options.
• Added new blocklist/allowlist options to permit fine-grained control of which files get packed.
  • A specific option was added to strip existing cubemap files from the map, if this is necessary to fix crashes while building cubemaps.
• Add transform to allow using /n in game_text messages to produce multiline ones.
• #167: Add comp_player_input_helper, an entity to trick Hammer into autocompleting player inputs.
• Transforms should now use EntityDef.engine_def(), not ctx.fgd to allow partially parsing the database.
• The postcompiler should now be able to parse Black Mesa's static prop format.
