Updated readme.rst
Fixed up some help strings of plugin commands
Moved catsplosion and regrass to normal plugin folder
Fixed tiletypes and liquids not keeping command history properly
* Paint, filter, and brush state is now saved between calls.
* Added 'all' paint option to set material, shape, special, and variant at
the same time.
* Added tiletypes-here (like liquids here, except is uses the saved brush
settings)
* Added tiletypes-here-point (like liquids here, always only the tile under
the cursor)
* Added tiletypes-command: runs tiletypes commands seperated by ';' tokens
(affects saved state)
* Make the internal workings match liquids a bit more
* Give brush objects a descriptor string
* Make Core::cheap_tokenise available
Removed t_virtual.
Made lua use C++ compiler
Removed many silly exception types from Error.h and renamed the rest.
Removed Brush classes from tiletypes plugin.
This is an incompatible change to the plugin ABI.
The Console is not thread-safe unless used indirectly
via color_ostream_proxy, so everything should use their
per-thread stream.
+ Able to set hidden, light, subterranean and skyview flags.
* Paint empty space correctly.
* Remove direction from directionless tiles.
* Remove liquid from walls correctly.
