0.5.1

Added:

• code to give more feedback to the user when the builder fails due to a database error

• regolith classlist can now read csv files in Columbia University format
• classlist register now checks whether a given file actually exists
• merge_collections to tools.py. merges two collections
• tests for manuscript review builder

• function for finding gaps and overlaps in lists of date-ranges
• utf8 support in all current latex builder templates

• function to dates that returns months as strings with leading zero where required
• function to dates that returns days as strings with leading zero where required

• ability to build publists with specified date ranges and filtered by grant
• tbd is now a valid month, returning 1 as an integer
• begin and end day now allowed in employment and education

Changed:

• unsegregated expense can now tolerate "tbd". This allows users to put a
  placeholder entry when the exact amount is not known, and then find it easily
  later. Code flags all tbd entries at build time, but doesn't crash.

• removed remote.rc logic from database.xsh
• current and pending builder extended to build c+p from merged proposal and grants collections
• added filter for cppflag so you can have current grants that don't appear in the current and pending form by setting cppflag to false in the db
• add needed_dbs statement for quicker building
• moved has_started, has_finished and is_current to tools.py

• Load only dbs needed for builder, if builder declares which dbs it needs
• reimbursement builder requires a person to be specified on the command line
  to run due to the extreme slowness of openpyxl

• User supplied schemas now handles new keys in regolith validate.

Fixed:

• valueschema -> valuesrules in schema as valueschema deprecated in cerberus

• cpbuilder does name comparison on fuzzy-searched name for standardization
• cpbuilder includes initials when it is a multi-pi grant
• filter_grants in tools.py bug fixed that incorrectly reassigns team members
• updated docstring on filter_grants to make it clearer
• fix indenting of the editor eyes only block

• import from collections.abc not collections
• months can now be expressed as ints or strings as per the schema
• fix bug introduced in Jinja2 v2.11 that doesn't recognize conditional text
  in the import
• bug so that needed_dbs results in only selected collections to be opened
• publist will now build even if person email and employment are missing
