2.0.0-alpha7

This is the seventh alpha release of our 2.0.0 "dev builds"; the major improvement in alpha7 is reduced light memory use.

The old stable v0.18.2-rc1 release still has more optimized output for Q1 and faster/less memory use for
qbsp/light, but we're working on regressions and welcome feedback as we work towards a stable 2.0.0 build.

Changes

• light: q2: opaque lit liquids receive light from both sides by default (specifically if they have the "warp" surf flag)
• qbsp: remove broken -transsky feature

Features

• bsputil: gained --svg export
• lightpreview: add camera bookmarks, stats panel with BSP lump sizes

Bug fixes

• qbsp: fix "sides not found" warning spam on Q1 maps with sky
• light: fix -dirtdebug causing a .lit file to be generated in Q2 mode
• lightpreview: fix -dirtdebug broken in Q2 mode (due to the above bug)
• light: reduce excess memory use

Enhancements

• qbsp: liquids are automatically detail (according to -transwater).
