If the user manually set the desired scale by calling scale.set(1.60)
the scale_level was not set accordingly which meant that later doing
a Scale:Increase/Decrease command yielded incorrect scale amount.
In TreeView:on_mouse_pressed() we need to find the directory a
relative filename belongs to from its absolute filename.
The code was using string.find to locate the relative filename
within the absolute path but in some very specific cases we can
find a pattern which is not the right-most one leading to a
wrong directory name.
Fix the error by adding a loop to make sure we find the right-most
match. The standard Lua library has not a string.rfind to make a
reverse search.

The method RootView:on_mouse_pressed was copied in the contextmenu plugin with
a small modification to intercept the mouse clicks of the active view.
This approach is problematic because a relatively large portion of code is
duplicated.
We introduced a function named RootView.on_view_mouse_pressed to let plugins
like contextmenu intercepts mouse clicks in the active area without duplicating
the function RootView:on_mouse_pressed.
Move the function mkdirp into common to be generally available.
Use the new common.mkdirp from create_user_directory() from
core/init.lua replacing previous parent directory creation code
within the function.
The previous mkdirp function did not work on Windows where
absolute paths starts with a drive letter. The code from
create_user_directory() did not have this problem but was wrong
in the way it was creating the nested directories.
The new implementation in common.mkdirp fix both problems.
Groups together consecutive mouse move events like done in core.step()
lua function but on the C side.
It does not introduce any meaningful speedup but it theory is more efficient and
simplifies the Lua code.
The simplification of the Lua code alone is enough to justify this change?
