Greetings Wizards!

This patch focuses on spell upgrades, with a few significant gameplay features as well, and a bit of new content sprinkled in as well. Read on:

General Gameplay:

Added combat log UI to game. Press m to open it. Hopefully comes in handy during some of the weirder more complex turns!
(For those who like to browse files: logs are now split per save, rather than overwritten each time. Furthermore, they are also available split by level and by turn, to make finding data easier.)

Inventory size is now limited to 10. I did this for 2 reasons- to discourage hoarding, to avoid situations where the player inventory is so large that the option space becomes overwhelming (something RW frequently struggles with!), and because I have no elegant UI solution for the player having so many items.

The Line of Sight algorithm has been changed from restrictive precise angle shadowcasting to permissive field of view. The gameplay impact of this change is that more squares are visible from any given square. The goal is to make LOS more intuitive and easy to guess- though of course the CTRL key still works.
(The previous choice to use the restrictive algorithm was driven by a desire to not allow beam spells to cause beams to penetrate through walls- the restrictive algorithm does this quite easily, but it turns out, it is also possible to construct beams between any 2 points visible with the permissive algorithm as well.)
If you'd like to read more about the two algorithms, check out roguebasins write up on the matter [url=[http://www.roguebasin.com/index.php?title=Category:FOV]]here[/url].

Creatures are now more willing to divert their path around stationary units blocking their path (stationary units which block a path are now counted as equivalent to a 50 tile detour, previously, they counted as equal to a 10 tile detour)

Fixed a bug where living scrolls would sometimes not disappear after casting themselves

Fixed a *myriad* of tooltips, rare crash bugs, and threat display bugs- thanks to the community for helping to find and identify these!

Levels will now tend to be bordered by either walls or chasms, so as to seem more like isolated realms. This was done purely for aesthetic reasons, but I like the gameplay effect of slightly lower max level size as well.

Spawner HP decreased by 1. (This reduces the number of casts required of 9 damage spell to kill a level 1 spawner by 1)

Reincarnation buff now reincarnates creatures with the same max hp and shields they had when they gained the buff

Fixed bug where creatures that respawned as others would use their current flyingness instead of new flyingness to determine an appropriate spawn point (resulted in vampires disappearing if you chased their bats deep enough into a big chasm)

Fixed bug where changing speed would close the options menu (dear fellow programmers: be careful with your gotos, and remember that break and continue statements are just gotos!)

Fixed some bugs with tab previewing of portals in deploy mode

Reworked achievement tracking. Achievements must now be earned on one machine- aka,, you cannot 5 winstreak on a desktop and a laptop at the same time (there are some edge cases here that are hard to resolve- what if you start 5 games on 5 machines simultaneously, and win them all? What if you simply leave the runs midway through, and keep buying more machines (or making more RW installations) until you have 5 good runs going, leaving the others in purgatory forever- is that a winstreak when you finish???). I'm a little bit sad that some of the simpler achievements (aka, 'get 5 wins') will now have to be completed on one machine, but this reduction in technical complexity will allow me to focus more on feature work and less on various maddening, hard to reproduce cheevo bugs.
