[Gretl-devel] function package updates

[Allin Cottrell]

A few fixes in today's CVS, pertaining to the menu item 
/File/Function files/On server:

* Remove redundant "Find" button (this can be reinstated when we 
have enough function packages on the server to warrant it).

* Add a "Call" button, to let the user try out a function from 
the server without installing it permanently.

* When the user does choose to install a package from the 
server, update this window appropriately (i.e. change "Not 
installed" to "Up to date" for the relevant file).

* Mark various strings in this vicinity for translation.

Please let me know of any breakage in this area!

Still to be done: set up a mechanism whereby function packages 
can signal their data needs (e.g. function X only works on time 
series data).

Allin.
