The algorithm used for breaking a paragraph in LaTeX export is changed
for avoiding spurious blank lines causing too much vertical space.
This change is tied to the introduction of a new inset (with two
different specializations) helping in either outputing LaTeX paragraph
breaks or separating environments in LyX. Both of the above goals were
previously achieved by the ---Separator--- layout and can now be
accomplished by the new inset in a more natural way. As an example,
after leaving an environment by hitting the Return key for two times,
a third return automatically inserts a parbreak inset, which is
equivalent to the old separator layout, i.e., it also introduces a
blank line in the output. If this blank line is not wanted, the
parbreak separator can be changed to a plain separator by a right
click of the mouse. Of course, an environment can still be separated
by the following one by using the Alt+P+Return shortcut (or the
corresponding menu key), but now the plain separator inset is used
instead of the old separator layout, such that no blank line occurs in
the LaTeX output.
Old documents are converted such that the LaTeX output remains unchanged.
As a result of this conversion, the old separator layout is replaced by
the new parbreak inset, which may also appear in places where the old
algorithm was introducing blank lines while the new one is not.
Note that not all blank lines were actually affecting the LaTeX output,
because a blank line is simply ignored by the TeX engine when it occurs
in the so called "vertical mode" (e.g., after an alignment environment).
The old ---Separator--- layout is now gone and old layout files using it
are also automatically converted.
Round trip conversions between old and new format should leave a document
unchanged. This means that the new behavior about paragraph breaking is
not "carried back" to the old format. Indeed, this would need introducing
special LaTeX commands in ERT that would accumulate in roundtrip
conversions, horribly cluttering the document. So, when converting a
modified document to old formats, the LaTeX output may slightly differ in
vertical spacing if the document is processed by an old version of LyX.
In other words, forward compatibility is guaranteed, but not backwards.
This patch implements 'move row' and 'move column' features for tabular.
The purpose is to provide a useful behavior in tabular that is
consistent with PARAGRAPH_MOVE_UP and PARAGRAPH_MOVE_DOWN so that the
user can, for example, do alt-<up> to move a row up. Alternatively,
icons for these features are also added to the table toolbar and
context menu.
If there is any selection, the feature is disabled. This is consistent
with how PARAGRAPH_MOVE_UP works in other contexts. Additionally, 'move
row' is disabled if there is a multi-row in the current or target row;
and 'move column' is disabled if there is a multi-column in the current
or target column.
'move row' moves only the left and right borders of a cell along with
the row. Similarly, 'move column' moves only the the top and bottom
borders.
Implementing similar functionality for other insets, such as arrays and
array environments, is on my TODO list.

"With LyX-2.0.1svn, if I open the context menu on a phantom (e.g.),
the Dissolve Inset item appears twice. This triggers a shortcut
conflict..."

This introduces a new LFUN LFUN_INSET_COPY_AS, which copies a certain Inset to the clipboard. For InsetInfo this is the text that is visible, but this could also replace LFUN_LABEL_COPY_AS_REF, by copying the INSET to the clipboard as a reference, and also a Math inset to copy to the clipboard as latex (including $'s or \[..\]).
