Include bibliography section in A1 and A2 for standalone document

[manuelfuenmayor]

Fixes #252

In this PR, I added the Bibliography section to Appendices 1 and 4 to fix the "references not found" issue.
And, in order to avoid conflict with the complete Brochure, I edited the lines attribute of the corresponding include:: directives to exclude the added bibliographies.

This change is applied to v3.01 only. Let me know if you agree with this solution, to do the same in the rest of the versions.

@manuelfuenmayor I've made my changes and this can merge now. Can you please make the same changes to 1.08 and 2.01 for consistency reasons? Thanks.

@manuelfuenmayor there is an error in a formula?

@manuelfuenmayor there is an error in a formula?

@ronaldtse the formula renders correctly on my side:

(The MathML code is a little large, so I leave it as text file: complex-formula.txt)

But when I test it on plurimath.org, it doesn't render.

Formula code:

{:(ii(E)_1, =, ii(A)_1 cos[ii(varphi)_1]),(ii(E)_2, =, ii(A)_2 cos[ii(varphi)_2]):}}  rarr I = langle (ii(E)_1 + ii(E)_2)^2 rangle_t = {ii(A)_1^2}/2 + {ii(A)_2^2}/2 + ii(A)_1 ii(A)_2 cos[ii(varphi)_1 - ii(varphi)_2]

Perhaps @suleman-uzair can help us in this case?

I've raised a ticket about it.

Merging.
