Load listings after babel (bug #8995)

Babel makes the character ':' active in french documents, and the listings
package cannot cope with that if it is loaded before babel. If it is loaded
after babel it works. This makes the french EmbeddedObjects manual compilable.
Add missing math delim decorations

This avoids a message "Deco was not found. Programming error?" on stderr.
The added decorations are defined by amsmath, and equivalent to \vert (single
vertical bar) and \Vert (double vertical bar), respectively. They are used to
distinguish the single and paired versions (for use with \left and \right).
These symbols should cause amsmath to be loaded, but this would be too
dangerous to implement now.
Fix misparsing of alternative simple formulas

This comes from trying to run tex2lyx on the AMS math test document
testmath.tex. Both \(...\) and \begin{math}...\end{math} are defined as
inline math formulas in standard LaTeX. tex2lyx recognizes this, but the
math parser in LyX did not handle "\begin_inset Formula \(" and
"\begin_inset Formula \begin{math}" correctly.
The fix is simple and safe: If we are in undecided mode (this is only true
for the first token of a math inset), create a hull inset of the respective
kind. Otherwise, handle the commands as before.
