* Fixed a problem that many of the exp requirements were 1 level off
* Removed custom level requirements from the default pre-re/re rAthena files
* Optimized the structure of these files; no more redundant data
* Added a few custom exp rows to import-tmpl/job_exp.txt that can optionally be used
* Updated 1st and 2nd trans job exp requirements to the new official values from 2015
* Fixed a bug that caused monsters to still give 1 base/job exp even though their exp in the db is 0
* Updated Summoner EXP requirements according to latest test results; as Summoner has exactly the same base exp requirements as 3rd classes starting at level 99, it will now use the same row
Add db/import-tmpl/ and add all file that could currently be
overwritten, (please add note if a db is missing)
db/import folder is created by "make import" just like conf/import and
msg_conff/import, (didn't found the visual equivalent)
