Since the directory monitoring is now basically working we remove the
project scan thread periodically scanning the project directory.
Each project's directory is scanned only once at the beginning when
calling the function `core.add_project_directory` and is updated
incrementally when directory change events are treated.
The config variable `project_scan_rate` is removed as well as the
function `core.reschedule_project_scan`.
Now we request a watch on the directory and we manage sending
and receiving directory change events.
The mechanism to update on the fly the directory scan is not complete.
The code to remove a file is there but we need to implement the code
to add a new file.
It is reported that the built-in lua function os.remove(path) does
not removes empty directories on windows. To fix this a system.rmdir
function is introduced that calls a native win32 function.
Also common.rm(path, recursively) was added which wraps system.rmdir()
to easily delete an entire folder with all its contents.
Add a renderer.font's method "copy" to clone the font object
by specifying an optional new size. In the size is not given
the size of the original object is used.
Should fulfill the request from issue #288.
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.
