add bibtex function to get the bibtex code for citing the sage components

[mwhansen]

This is a follow-up to the BibTeX idea from #1348:

6.3 how do i reference sage?
If you write a paper using SAGE, please reference computations done with
SAGE by including
[SAGE], SAGE Mathematical Software, Version 2.6, http://www.sagemath.org
^^^
How about a function bibtex() similar to latex() which gives a bibtex
entry? Coudl default to bibtex(sage) but could also provide
bibtex(pari), bibtex(gp), bibtex(Singular), etc.

This is an excellent idea. The output should probably be both the bibtex
database entry and the result of running it through bibtex, so it can be directly included in a paper (without having to use bibtex).

This information is in the FAQ. Is it worth introducing a command for it? I am a little dubious: the command would be redundant, and it would be easy for the FAQ and the command to get out of sync. I propose that we close this.
