[tlbuild] asymptote search path

Hi all,

Uninstalling one version of asy (perhaps before installing another version)
should certainly not remove the history files ~/.asy/history*
(which contains data typed by the user).

In svn (will be in the 1.83 release, which is planned for tonight), I have
changed item 3 in the Asymptote search path:

1. The current directory;

2. A list of one or more directories specified by the configuration
variable dir (separated by : under UNIX and ; under MSDOS);

3. The directory specified by the environment variable ASYMPTOTE_HOME; if
this variable is not set, the directory .asy in the user's home directory
(%USERPROFILE%\.asy under MSDOS) is used;

4. The Asymptote system directory (by default, /usr/local/share/asymptote under
UNIX and C:\Program Files\Asymptote under MSDOS).
