Add to Favorites - selection mode - add /m /-m

[ProgerXP]

Add two new radio buttons to #249:

• Fi&rst substring
• Las&t substring

They create an LNK like Current line/selection but using either /m or /m- switch. Because Windows command-line quoting rules are strange, these radio buttons are disabled if any of this is met:

• rectangular selection
• empty selection
• selection contains " or non-printable symbols (such as line breaks)
• selection is too long

You can determine more limitations on last two points.

Done.

(wcspbrk(lpParams->pszCurrentSelection, L" \t\r\n\"") != NULL))

No need to forbid the space - simply wrap the parameter in ". As for \t - yes, it's invalid, I doubt LNKs can handle it.

[cshnik]

Fixed. Space character is now allowed.

1. Make radio buttons' click area last until the end (see how it's done in Windows, e.g. Folder options in Explorer).
2. Update radio button texts to this:

"&First line"
"L&ast line (/g -1)"
"&Current line (/g)"
"Current &selection (/gs)"
"Fi&rst substring (/m)"
"Las&t substring (/m-)"
