Make Copy with included titles compatible with Paste

[cheater]

Currently if you use the Copy function with "include titles" enabled, and then use the Paste function, the titles will be opened as separate tabs.

Currently the "Include titles" option creates strings of the following format:

https://github.com/joshdick/tabclip/issues/new | New Issue · joshdick/tabclip
https://www.google.com/ | Google

However, if you made it like this:

https://github.com/joshdick/tabclip/issues/new # New Issue · joshdick/tabclip
https://www.google.com/ # Google

and made tabclip ignore everything after a space and a # sign, then that would fix the issue. It feels like it's probably safe to ignore stuff after such a string. However, you do allow the literal space as part of a URL, which may make it confusing for people when they try to paste a URL that does contain a literal space followed by a # sign. On the other hand, the literal space normally never shows up in URLs - links escape those as + or as %20. When you copy URLs out of the address bar, the same thing happens. Finally, tabclip itself escapes those as %20 as well.
