[ReviewEntriesTable] Consider bulk actions

[imnasnainaec]

Feedback from Hasso:

• Our participants generated a number of multi-word phrases that don’t belong in the dictionary. Marsha was able to filter for Vernaculars with spaces (good), but had to delete each entry one at a time with confirmation for each. Because her screen is small and the trash can is at the far left, she had to scroll back and forth to look at the vernacular and then delete each entry.
• ~One user didn’t realise the need to scroll to the bottom of the list before clicking the arrow to navigate to the next page of ten.~
• Nice to have: bulk flag entries (say, if there are multiple words that may be misspelled).

The bulk actions call for different user interaction, and may need it's own tool, not just changes to Review Entries. In addition to the bulk delete and bulk flag requested, also bulk part of speech.
