In Isabelle2020, when isabelle jedit is started without a session
context, e.g. `isabelle jedit -l ASpec`, theory imports with path
references cause the isabelle process to hang.
Since sessions now declare directories, Isabelle can find those files
without path reference and we therefore remove all such path references
from import statements. With this, `jedit` and `build` should work with
and without explicit session context as before.

Isabelle LaTeX style files use old font commands \bf, \rm, \tt, etc.
However, newer versions of some LaTeX document classes (e.g. scrbook)
have removed support for these commands. This brings back those
commands for documents built with isabelle.sty.
The only major change is that "embed" is now a constant in HOL, removing
it from the set of valid names for free variables.
Have renamed uses of "embed" to "embed_data"; a better name could
probably be chosen by someone more familiar with the code.
