I've had to write my own tiling code as WM_MDITILE will not fit
windows to the edge of the MDI area. My code tries to mimick
WM_MDITILE as closely as possible.
5.Item 13, changed.
6.Item 14, added. This tries to parse and sort items in a way
that groups similar items together.
7.Item 15, added. Using an undocumented method for scrolling in
menus. It works all the way back to Windows XP, so seems
reliable.

Beta v7.64.4889 changes:
1.Item 1, added.
2.Item 2, reverted.
3.Item 3, updated. Also removed error codes from the messages in
resources as we already know them. I would have preferred to use
FormatMessage() as it returns error messages in the system
language but its messages are long and descriptive as opposed
to mIRC's short, compact messages.

7.Item 7, udpated.
8.Item 8, updated.
9.Item 9, needs testing.

MDI windows in Windows 10 currently use the Windows 7 theme, due
to Microsoft deprecating support of MDI windows. This beta adds
Windows 10 Aero theme support to MDI windows. This is enabled
only for MDI windows and only when the Windows 10 Aero theme is
in use.

I have had to make a number of design decisions regarding colors,
borders, button sizes, and so on, to approximate the look and
feel of the Aero theme. I am fairly happy with the result. It is
not an exact match to Aero but close enough, with the aim being
to make MDI windows look reasonably up-to-date.

Changes:
1.Added flash option to ignore dialog options.
2.Reverted change to nick idle time so that it is updated per second
once again.
3.Updated some of the winsock error messages in resources to use more
up-to-date descriptions.
4.Fixed regex global matching bug with UTF-8 characters.
5.The styles dialog has been removed. The channel nicklist sizing
bar now uses a standard width. The editbox and nicklist borders now
use standard Windows colors. Windows no longer use an internal frame.
6.Fixed tray tips Control+O display bug.
7.Updated OpenSSL library to v1.1.1j.
8.Updated TagLib library to v1.12.
9.Added Windows 10 Aero theme support to MDI windows.
10.Changed the aliases list menu to use shorter, combined a-z menus,
with separators, and any left over items in a ? submenu.
11.Fixed URLs List SendTo menu item being disabled.
12.Fixed MDI tile feature not fitting the right/bottom-most windows
to the edge of the MDI area.
13.Changed scripts editor alias and popup menubars to use an "Index"
menu name to list aliases/popups.
14.Added scripts editor "Index" menu to remote menu bar that lists all
of the items defined in a script. It also includes partial lines
for some items to give context.
15.Added home/end/page up/down key support to popup menus to allow
for faster scrolling in long menus. These keys normally do nothing
in menus, however they will now scroll multiple lines per key press
and will stop once they reach the top/bottom of the menu.
