Problem: Some "gomod" files are not recognized.
Solution: Check for "go.mod" file name before checking out the contents.
(Omar El Halabi, closes#12462)
Problem: .fs files are falsely recognized as forth files.
Solution: Check 100 lines for something that looks like forth. (Johan
Kotlinski, closes#12219, closes#11988)
MacVim's `:hardcopy` implementation just uses Preview to show the
generated PostScript file and lets the user decide what to do with it.
macOS 13 Ventura removed PostScript support from Preview, so we now have
to manually convert it to PDF first using `pstopdf` (which is thankfully
bundled with macOS).
While we are at it, update the script so that we actually delete the
file after sending it to Preview. Previously MacVim never did that and
therefore leaks the file in a temp folder until Vim closes, which isn't
ideal for privacy. Now, just set a 10 sec timer to delete the file after
it's opened (we just need enough time to allow Preview to open and load
the file, which doesn't take much time. The 10 sec timer is to account
for slow computers).

Problem: Conflict between supercollider and scala filetype detection.
Solution: Do not check for "Class : Method", it can appear in both
filetypes. (Chris Kipp, closes#11699)
Add a new Vim script function `showdefinition()` that allows Vim script
to call back to macOS's data lookup feature and show the definition /
URL preview / etc for any text, at a designated row/col position. If the
row/col are not provided this function will just show it at the cursor.
Also, add a new autoload/macvim.vim for utility functions to call
showdefinition() for selected texts and the word under cursor. Make a
new right-click popup menu "Look Up" call that when there are selected
texts in visual mode to make the lookup functionality easier to access
for users without a trackpad (since Ctrl-Cmd-D is a little obscure and
unwieldy to use). For the utility functions, it was a little hard to
determine how to get the text under visual selection without yanking (we
don't want to pollute the register here), and just implemented a
function to take care of all the edge cases including visual/block/line
modes and selection=exclusive. It could be useful in other situations.
As a side refactor, change the message handler in MacVim from if/else to
switch case. In optimized builds, they both essentially optimize to the
same thing, but for debug builds, the if/else statements have to step
through one by one, and switch case just makes more sense for a giant
message ID lookup like this.
