This allows for users to change the colors if needed (may be useful
with some themes or color blind persons).
On the sidebar, only the color is applied for now. This is because
it is not possible to style cell renderers through RC files, all having
to be done in the code; so currently only the color is applied.
This allows the user to override the custom styles we apply to some
widgets, like e.g. the unmatched search entry colors.
We use the :theme priority rather than the :application one because
it seems that the :application one cannot override theme settings, even
if it matches against a name the theme don't have rules for but have
rules for the class of that widget. This prevents a theme from
overriding our styles, but it's unlikely a theme actually provide some
specific stuff for us anyway.
"default" was mapped to "value" which is normally a string-like
style rather than a "default" type of style which make some themes
that set different background colour for strings to look weird for
config files highlighting.
Although using menu items for these is not very practical, it helps
discoverability, and they're more useful and intuitive than 'Transpose
Current Line'.
This copies the current document text and properties into a new
document, similar to the old Save As 'Open file in a new tab'
option, but easier to understand and decoupled from saving.
One notable difference is that the new document does not copy the
filename - the old behaviour was confusing and error-prone for the
user (e.g. editing two documents with the same filename).
With newer GTK+ releases, leaving this field blank causes the "Recent
Files" "feature" to be used rather the the expected current working
directory. No replacement text added to explain the new behaviour since
it would be incorrect with older GTK+ versions, would likely be incorrect
on Windows with native dialogs and it will possibly be reverted in GTK+
in the future.
Recenerate HTML manual, including previous changes from other commits.
Now there is a dialog instead of a menu for selecting the color
schemes, the item under View->Editor can be created with Glade like the
rest of the menu.
