Hammer Editor Extensions addon - Portal 2

Introducing an addition to Portal 2's Hammer editor that's even larger than the last one!
This one not only includes nearly every model and texture (currently, there are issues with textures being overridden due to matching names, and some models just aren't appearing for some reason) from Portal 1, but also from Half-Life 2 (including beta textures, such as building templates.)!
Major note: Due to the immense increase of items, the searcher for models may crash the game if too many items load, also, try avoiding npc models, though the metro-cop should be fine!)

Simply place the three files into the game's (under Portal 2/portal2, just like for Retro Portal), and enjoy!

Any issues? Let me know!

(Note: I will try to fix the textures that are being overridden (examples: observation wall textures) in the future.)
