opening errors in tide-project-errors creates many windows

[nahuel]

When you open an error by pressing RET on a tide-project-errors window, a window is always created if the related file buffer is not already shown in one. So navigating through multiple project errors opens many windows, a very annoying behavior. It will be nice to make tide-goto-error always reuse the same window when the buffer is not shown.

It also will be nice to also add a command like tide-goto-error, maybe called tide-view-error which not switches to the other window when showing the error, to quickly browse through all the project errors.

Also adding a tide-project-next-error/prior command to navigate errors without opening a tide-project-errors window will be nice.
