Glyph adjustments

Hi there!  First of all, thank you so much for the excellent game.  I play it all the time, and my 4 year old daughter loves playing too (well, with me given the difficulty and everything =) ).

So, I wanted to present a couple of ideas for you consideration.  First, the nighttime mode adjustment.  I'm probably a big wuss, but I almost never get to play in night mode because I'm never up that late, so maybe widening that mode a bit will allow more people to experience it?

Second, the armor glyphs.  Many people on the PD wiki/forums consider the glyphs to be less than great (except for metabolism, which seems way overpowered?).  So, I reworked most of them and they feel more balanced now IMHO.  The ones that damage the player deal less damage, and some of the riskier effects are replaced (eg. setting the player on fire w/ anti-entropy is a massive liability, especially before scroll holder).

Also, I changed the proc rates with a more standard mechanic (eg. procs ~1 in 10 for +0 armor, about 1 in 2 for +5).  Hopefully I have that math right.  Definitely open to input on this one though.

Let me know what you think.  Thanks!
