Notepad_plus_Window was rather huge (megabytes). Now it's small (tens of kilobytes),
but to safeguard against future size increase move its allocation from the stack
into the heap.
By using smart pointer, this PR not only fix open file crash properly,
but also prevent stack from being corrupted in the future.

LexerStylerArray contains a MAX_LEXER_STYLE-element array (currently 100) of LexerStyler objects. Every one of them in turn via inheritance from StyleArray contains a SCE_STYLE_ARRAY_SIZE-element array (I tested with 99) of Style objects each at least 56 bytes in size. This in my test case requires over 550k of memory, and if LexerStylerArray is allocated on stack, the stack becomes corrupted.

Inline arrays are a part of an object and increase its size while std::vector uses memory from the heap and stores internally only a pointer to a chunk of memory, thus the size of an object with a vector is substantially smaller than the one with an inline array.

Now take that into account when searching the button.

This PR uses always current buffer's path in Find in Files dialog:
When "Follow current doc." is checked, then use current path first.
If that fails, fallback to the working directory as it was before.

The plugins' toolbar icons can be displayed in both light/dark mode by using their original icons.
Though using new API NPPM_ADDTOOLBARICON_FORDARKMODE to have better look & feel is recommanded.

Add Markdown UDL of dark mode and the ability to apply it:
After dark mode being swiched in, all files with extension .md will be opened by applying Markdown UDL of dark mode.
When light mode is switched back, the default Markdown UDL (of light mode) will be applied to the new opened .md file.
Please note that all .md files opened before switching to new mode, will remain in the previous mode. User has to close and reopen these files to have the right Markdown UDL applied.
